A line is drawn so that it passes through the points (15,-3) and (17,5). What is the slope of the line?

m = 4

Step-by-step explanation:

We know that,

( 15 , -3 ) ⇒ ( x₁ , y₁ )

( 17 , 5 ) ⇒  ( x₂ , y₂ )

You have to use y = m x + c to find the equation of the line.

Here,

m = slope

c = y - intercept

Let find the slope now.

Slope = 4

Hope this helps you.

Let me know if you have any other questions :-)

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
