Find an equation of the line that goes through the points (2, -8) and(-1, 1). write your answer in slope-intercept form.

y = -3x - 2

Step-by-step explanation:

As we move to the right from (-1, 1) to (2, -8), x increases by 3 and y decreases by 9.  Hence, the slope of this line is m = rise / run = -9/3 = -3.

Start with the general slope-intercept form:  y = mx + b.

Substitute -8 for y, 2 for x and -3 for m:

-8 = -3(2) + b

So, b = -2, and the desired equation is y = -3x - 2. Note that (-1, 1) satisfies this equation.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
