Write the equation of a line whose slope is -2 and passes through (-1,6). write the answer in slope-intercept form.

Y = mx + b
slope(m) = -2
(-1,6)x = -1 and y = 6
now we sub and find b, the y int
6 = -2(-1) + b
6 = 2 + b
6 - 2 = b
4 = b

so ur equation is : y = -2x + 4 <==

We are given an (X, Y) in (-1, 6). We are also given a slope of -2.

Start by plugging all those values into the slope intercept equation.

6 = -2*-1 + B

Solve for B.

B = 4

Now, all you have to do is put it back into the equation again, this time not using the (X,Y) we had initially, but just the slope (-2) and our new "B" value (5).

The resulting equation looks like this:

y= -2x + 4

And that's the answer.

That’d be 9 years or something
