Question

What is the equation of the line through (4, 5) and (0, -3)?

A. y = 2x+ 3

B. y = 2x - 3 X)

C. y = -2x + 3

D. y=-2x-3

(put your answered letter in the answer box)​

Answer 1

Answer: A. y= 2x-3

Step-by-step explanation: APEX,

Slope intercept equation of a line:

y = mx + b

(0, -3) is the y-intercept, so b = -3

We have

y = mx - 3

Now we use the two points to find the slope.

slope = m = (-3 - 5)/(0 - 4) = -8/(-4) = 2

y = 2x - 3
