Equation of a Linear Equation

Identify the slope-intercept equation:

• y = 2x - 2

• y = -2x + 2

• y = -2x + 4

• y = 2x + 4

Answer explanation

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. The correct choice, y = 2x + 4, has a slope of 2 and a y-intercept of 4, fitting the slope-intercept format.

Write the equation of the line in slope intercept form.

Answer explanation

The correct equation in slope-intercept form is y=\frac{1}{3}x-2, where the slope is \frac{1}{3} and the y-intercept is -2. This matches the second answer choice.
