Write an equation in slope-intercept form for this line.

y=3/2x+2

Step-by-step explanation:

y-y1=m(x-x1)

m=3/2

y-8=3/2(x-4)

y-8=3/2x-12/2

y-8=3/2x-6

y=3/2x-6+8

y=3/2x+2

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
