Y = mx + b

m = slope, b = y-intercept

m = -3, therefore the slope is -3

Subtract 2 from both sides:
y−2=−3x

Divide both sides by -3:
- y-2/ 3 =x

switch sides:
x- y-2/3

Answer: x- y-2/3

1. A line passes through (9, -9) and (10,-5).
jenyasd209 [6]

Answer:

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
