Which is the equation of a line that has a slope of 1/2 and passes through point (2,-3)

y=1/2x-4

Step-by-step explanation:

y-y1=m(x-x1)

y+3=1/2(x-2)

y+3=1/2x-1

y=1/2x-4

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.
