Question

Complete the eqaution of the line through (-8, -2) and (-4, 6)

Answer 1

y = 2x + 14

Explanation:

y = mx + b to write the equation, we need 2 things: the slope and the y-intercept

y = ___x + ____

Slope:

Change in y over the change in x. We find the change by subtracting. The y values are 6 and -2. The x values are -4 and -8

`(6- (-2))/(-4 -(-8))` =
`(6+2)/(-4+8)` =
`\frac{8}4}` = 2

The slope is 2.

y-intercept:

Use either of the points given and the slope 2 to find the y-intercept. I am going to use the points(-4,6). I will use -4 for x and 6 for y given from the point

y = mx + b

6 = 2(-4) + b

6 = -8 + b Add 8 to both sides

14 = b

The y-intercept is 14.

y = 2x + 14
