1. A line passes through (9, -9) and (10,-5). a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.

1. y+5=4x-40

2.y=4x-45

Step-by-step explanation:

To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4

Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45

answer:

your answer is: c. 196 7/8 in^3.
