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.
