Write an equation in point-slope form for the line that passes through the given points (1-3), (1,-15)

x = 1

it's a horizontal line

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.
