Question

What is (-4,5) and (8,-1)

Answer 1

Answer:

the slope-intercept equation of a line that passes through the coordinate (-4,5) and (8,-1) is

$y = - 0.5x + 3$

Step-by-step explanation:

1) Apply the slope formula; y^2 - y^1 divided by x^2 - x^1

y^2 is -1

y^1 is 5

x^2 is 8

x^1 is -4

-1 - 5 = -6

8 - (-4) = 12

-6/12 is -1/2 or -0.5

2) To find the y-intercept, hoose either of the coordinates and replace y, m, and x in the y= mx+b formula.

5= -0.5(-4) + b

5= 2 + b

3= b
