Question

Write the equation of the line that passes through the given points
(0,- 4) and (5,4)

Answer 1

y=8/5x-4

Explanation:

1:find the slope

`(4+4)/(5-0) =(8)/(5)`

slope/m=8/5

2: solve for b using Y=mx+b

plug in the numbers to find b (the x and y get from one set of the points your given and the m is the slope)

Y=mx+b

y=4

m=8/5

x=5

4=8/5(5)+b

4=8+b

-4=b

than to put all the in y=mx+b form just plug in the b and m
