Answer:

Slope: -1

y-intercept: 6

Explanation:

Lets figure out the slope with the formula,
(y2 - y1)/(x2-x1). Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:


(7-9)/(-1-(-3))


(-2)/(-1+3)


(-2)/(2)


-1

Now we know that the slope is -1, so m = -1.

Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:

1 = -5 + b

b = 6

Now we know that the y-intercept is 6, so b = 6. I hope this helped!
