Answer: m = -1 b = -5

Explanation:

Rewrite the equation in "slope-intercept form" y = mx +b .

m is the slope

b is the y-intercept, where the graph of the line crosses the y-axis

To rewrite the equation, to get "y" alone on the left side, subtract x from both sides:

x + y = -5

-x + x + y = -x - 5 (left side -x +x =0 so "cancel")

y = -x -5

You get the slope "m" from the coefficient of x, (invisible 1, sometimes)

since there is a negative sign, the coefficient is -1 That is m, the slope.

A negative slope goes down from left to right.

For -1, down one over 1 square.

Your graph should look like the screenshot below.

I hope this helps you understand better!

X+y=-5

-x -x

y=-x-5 is the ending equation.

How to graph:

The y-intercept, or point where the graph starts, is -5

From there go down 1, right 1.

M=-x

B=-5
