y=mx+b

anonymous · Answer

y = mx + b

Where 'm' is the slope and 'b' is the y-intercept.

anonymous · Answer

So plug in '3' for 'm' and '-2' for 'b' and you have your equation.

anonymous · Answer

The equation is y = mx + b where m is slope and b is y-intercept, so can you figure out the answer by plugging in the values in the question? @lolcat

anonymous · Answer

so A

anonymous · Answer

Yep!

Also, y-intercept is when x=0 :P

anonymous · Answer

Yes, the answer is A! Great job! :)

Or just where the line touches the y-axis. @Luigi0210
