Aline has a slope of -2 and passes through the point (1,-2). what is an equation of this line ?

y=-2x

Step-by-step explanation:

we know linear functions can be in slope-intercept form: y=mx+b.

we are given the point (1,-2) so x=1 y=-2 and m=-2 because the slope is -2

so lets plug that into the slope-intercept form

y=mx+b

-2=-2(1)+b  multiply

-2=-2+b   add two on both sides

0=b

so it has the form y=-2x+0 aka y=-2x

answer: the answer is 127 degrees
