Point Slope Formula

POS
Write the equation of a line given two points.
(1.3) and (-3,-5)
First, find the slope between the two lines and enter that answer below. Remember to simplify your fractions.
m =
Then use your slope to find the equation of the line
y =

Answered by admin @



Answer:

y = 2x + 1

Step-by-step explanation:

Slope formula is y2-y1/x2-x1

-5-3/-3-1

-8/-4

2

Thus, the slope is 2 (m = 2)

Find the y intercept.

y = 2x + b

3 = 2(1) + b

3 = 2 + b

1 = b

y = 2x + 1

Best of Luck!
