y=-9x-10
y=mx+b
where b= y intercept
and m=slope

First recall the slope-intercept form is: y = mx + b
f(x) is simply another way of saying 'y'.
y = -9x -10
.
The slope = m= -9.
.
The y-intercept is where x=0, which means y = -10.
.
Graphing is a good way to check, but you need to points to draw a line.
At this point, you have only one point: (0, -10).
.
Another good one to find is the x-intercept, which occurs when y=0.
.
0 = -9x -10
9x = -10
x = -10/9
.
So the point is (-10/9, 0)
.
