abb0t · Answer

Rearrange it into standard form:

y = mx+b

m is your slope
b is your y-coordinate value

anonymous · Answer

so how do set it up? where does the -4 and 2 go?

abb0t · Answer

plug it in for x, and y...

abb0t · Answer

You could also use Calculus and find the derivative of the function.

anonymous · Answer

i need to know step by step how to work this i dont understand

terenzreignz · Answer

Firstly, what's the slope of
y + 7x = -20
?

anonymous · Answer

7 ?

terenzreignz · Answer

No.
First, arrange it in this form
y = mx + b
It's important that y is alone on one side, with no coefficients or negative signs.
Once it is in this arrangement, whatever is the coefficient of x, that's the slope.

So again, what's the slope of
y + 7x = -20
?

anonymous · Answer

is it -7 ?
