2. If the slope is 5 and the line passes through (-2, -3), what is the equation of the line in point-slope form? *

A. y + 3 = 5(x + 2)
B. y - 3 = 5(x + 2)
C. y + 3 = 5(x -2)
D. y -3 = 5(x - 2)

Point-slope form:  y - y₁ = m(x - x₁)

(m is the slope, (x₁, y₁) is the point you are given that is on the line)

You know:

m = 5

(x₁, y₁) = (-2, -3)         So substitute/plug it into the equation

y - y₁ = m(x - x₁)

y - (-3) = 5(x - (-2))   (two negative signs cancel each other out and become positive)

y + 3 = 5(x + 2)    Your answer is A

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
