Best ResponseYou've already chosen the best response.1but an example assuming you are given a graph: we want slopeintercept form for: the line hits the yaxis at 3 ( this point is (0,3) and the line hits the xaxis at 1 (this point is : (1,0) so to find the slope you do: \[\frac{y_1y_2}{x_1x_2}=\frac{30}{0(1)}=\frac{3}{1}=3 \\ \text{ now we know the } yintercept=3 \\ \text{ so this equation in slopeintercept form is } \\ y=mx+b \\ \text{ where } m=\frac{y_1y_2}{x_1x_2}=3 \text{ and } b=yintercept=3 \\ \text{ so that is the final answer to my example} \\ y=3x+3 \\ \text{ checking...} \\ y=3(0)+3=3 \text{ good } \\ y=3(1)+3=0 \text{ good } \]

Best ResponseYou've already chosen the best response.1in your picture you can clearly identify the yintercept and the xintercept so proceed to finding the slope

Best ResponseYou've already chosen the best response.0What is the equation of the line in slopeintercept form? y = 36x − 3 y = −3x + 36 y = −3x + 12 y = −12x + 3

Best ResponseYou've already chosen the best response.1and you really don't have to do any math on this one the choices given make the answer really obvious since the yintercept is...

Best ResponseYou've already chosen the best response.1what number does your line hit on the yaxis?

Best ResponseYou've already chosen the best response.1whatever number you say (if you look at the right axis anyways) you can replace the b in: y=mx+b with it
