Question

What is the equation for a line that passes through the points (2,-2) and (-4,16)?

Answer 1

-3x+4

Explanation:

In order to find the slope, you need to use this formula:
`(y_2-y_1)/(x_2-x_1)`. Insert the coordinates and see that the slope is -3. In order to have the points (-4,16) and (2,-2), the y-intercept is 4. In the end, the line is -3x+4.
