Find the slope and y-intercept of
y=-4x-9

Formula:
Y=Mx+b
(Basically its like this: Y=Slope(x)+Y intercept)
The M will always be slope, and the b is always going to be the y intercept.
So, all you have to do now is find them.
y=-4x-9
y=-4(slope)x-9(y intercept)
So, -4 is the slope, and the y intercept is -9

~Hope this helped :)

Y = - 4x - 9

y= mx + b

m is the slope
b is the y-intercept

so -4 is the slope
and notice that it has -9 not +9 so:

the y-intercept is -9
