f(x)= -9x-10

What is the slope
and the y-intercept I have no idea how to do this. Please help

6x+7y=39
x=50-6y

what is the solution of the system

f(x)=-9x-10

if you read your text it states that slope intercept form is y=mx+b where m is the slope here -9 and b is the y (or f(x) )intercept -10.

to find the solution to the system look at the solution I gave for your other problem and use the same technique
