Question

What is the equation of this line in slope-intercept form?

y=−3x−1

y=−13x−1

y=3x−1

y = 3x + 1

Answer 1

y=−3x−1

Explanation:

I took the quiz

Answer 2

The correct answer is A) y = -3x - 1

In order to find this, start by using the two points on the line to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - 2)/(1 - -1)

m = -6/2

m = -3

Since A is the only one with a -3 slope, this is the correct answer.
