What is a linear equation in one variable?

A linear equation in one variable is an algebraic equation that can be written in the form ax + b = 0, where 'a' and 'b' are constants and 'x' is the variable. The graph of a linear equation in one variable is a straight line, and the solutions to the equation are values of 'x' that make the equation true.

How do you solve a linear equation by using the addition or subtraction property of equality?

To solve a linear equation using the addition or subtraction property of equality, simply add or subtract the same value from both sides of the equation in order to isolate the variable. By performing this operation, you will be able to solve for the variable and find the solution to the equation. Remember to always perform the same operation on both sides of the equation to maintain the equality.

How do you solve a linear equation by using the multiplication or division property of equality?

To solve a linear equation using the multiplication or division property of equality, you can multiply or divide both sides of the equation by the same non-zero number. This maintains the equality of the equation. By doing so, you isolate the variable on one side of the equation to find its value. Remember to perform the same operation on both sides of the equation to maintain balance and find the correct solution.

What is the slope-intercept form of a linear equation?

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line intercepts the y-axis. This form is commonly used to represent linear equations because it clearly shows the relationship between the slope and the y-intercept of the line.

How do you graph a linear equation using its slope and y-intercept?

To graph a linear equation using its slope and y-intercept, first plot the y-intercept as a point on the y-axis. Then use the slope to determine a second point by moving up or down according to the slope (rise) and right or left (run) on the x-axis. Connect these two points with a straight line to represent the linear equation. Repeat the process to plot additional points if needed.

What is the standard form of a linear equation?

The standard form of a linear equation is Ax + By = C, where A, B, and C are constants, and A and B are not both zero.

How do you convert a linear equation from slope-intercept form to standard form?

To convert a linear equation from slope-intercept form (y = mx + b) to standard form Ax + By = C, where A, B, and C are integers and A is non-negative, you simply need to rearrange the terms. Start by moving the x-term to the other side of the equation by subtracting mx from both sides, which gives you -mx + y = b. Next, multiply all terms by a common multiple to clear the fractions, resulting in A(x) + B(y) = C, where A, B, and C are integers.

How do you find the x-intercept of a linear equation graphically?

To find the x-intercept of a linear equation graphically, look for the point where the graph intersects the x-axis. At the x-intercept, the y-coordinate is 0, so visually identify the point where the line crosses the x-axis, and the x-coordinate of that point would be the x-intercept of the linear equation.

How do you find the y-intercept of a linear equation algebraically?

To find the y-intercept of a linear equation algebraically, you can set the x-value in the equation to zero and solve for the y-value. This is because the y-intercept is the point where the line crosses the y-axis, which is where x is equal to zero. By substituting x=0 into the equation and solving for y, you can determine the y-intercept.

How do you solve a system of linear equations using graphing or substitution method?

To solve a system of linear equations using the graphing method, you graph each equation on the same coordinate plane and find the point where the two lines intersect, which represents the solution. Alternatively, the substitution method involves solving one equation for a variable and substituting that expression into the other equation to find the value of the remaining variable, eventually solving for both variables in the system. Each method has its benefits and can be used depending on the complexity of the equations or personal preference.
