Question

What’s the equation of the blue line?

Answer 1

Answer:

Step-by-step explanation:

(-1, 2) (0, -1)

(-1 -2)/(1 + 0) = -3/1 = -3

y - 2 = -3(x + 1)

y - 2 = -3x - 3

y = -3x - 1

Answer 2

Uee two points on the line to find the slope.

(-1,2) and (1,-4)

Slope = change in y over change in x;

Slope = (-4  - 2)/ (1 - -1) = (-6/2) = -3/1 = -3

The y intercept is y value where the blue line crosses the y axis, which is at -1

The equation would be y = -3x-1
