Question

HELP PLEASE!!!! I dint understand this and I only have to 12!

Answer 1

y = -6x

Explanation:

Take 2 points:

(-1,6)

(1,-6)

Find the slope:

-6 - 6/1 - - 1

-12/2 = -6

So we have the equation:

y = -6x + b

now to find b, insert one of the points from before for x and y

-6 = -6(1) + b

-6 = -6 + b

b = 0

So then we get y = -6x + 0 which we can write as y = -6x

Answer 2

Answer: y = -6x

==========================================================

Work Shown:

Two points on this line are (0,0) and (1,-6)

The slope of the line through these points can be found through the slope formula

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

m = (-6-0)/(1-0)

m = -6/1

m = -6 is the slope

The y intercept is b = 0 as this is the location on the vertical y axis where the graph crosses.

Using m = -6 and b = 0, we go from y = mx+b to y = -6x+0

This simplifies to y = -6x
