Question

Write the equation of line , in slope-intercept form, given the points A(0, 4) and B(-4, -8). In your final answer, include all of your calculations.

Answer 1

Answer:

y=3x + 4

Step-by-step explanation:

Slope intercept form: y=mx+b

M is the slope, and b is the y-intercept.

(0,4) (-4,-8)

(X2, y2) (x1, y1)

M= Y2-y1

______

X2-x1

M = 4 - (-8)

______

0 - (-4)

M = 4+8

___

0+4

M = 12

___

4

Slope: 3.

Y-intercept : 4.

Answer: y=3x+4
