Question

how do you do this why does it make me put so many words

Answer 1

Part 5

we have the points

(0,4) and (4,8)

Find the slope

m=(8-4)/(4-0)

m=4/4

m=1

Find the equation in slope intercept form

y=mx+b

we have

m=1

b=4

so

y=x+4

Part 6

we have the points

(0,8) and (2,4)

m=(4-8)/(2-0)

m=-4/2

m=-2

y=mx+b

we have

m=-2

b=8

so

y=-2x+8
