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


y=−3x−1

y=−1/3x−1

y=3x−1

y = 3x + 1

Answer 1

Answer:

y=-3x-1

Step-by-step explanation:

This is the answer because the y intercept is at -1 and the pattern is down 3 right one so therefor y=-3x-1 is the answer

Answer 2

Slope-intercept form is:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

You need to find "m" and "b".

If you look at the graph, at x = 0, y is -1, so the y-intercept is -1.

y = mx - 1

To find the slope, you use the slope formula, and plug in the points (-1,2) and (1,-4):

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{-4-2}{1-(-1)}$

$m=\frac{-4-2}{1+1}$

$m=\frac{-6}{2}$

m = -3

y = -3x - 1     The first choice is your answer
