Question

anonymous · Answer

the equation for slope is y = mx + b. this is slope intercept form

anonymous · Answer

m is the slope, and b is the y intercept.

how would i write that?

anonymous · Answer

subtract the x1 and y 1 then x2 and y2

anonymous · Answer

that is your slope.

abb0t · Answer

Find the slope first: $\sf slope=m=\frac{\Delta y}{\Delta x}\frac{y_2-y_1}{x_2-x_1}$

ABBOT LET ME HANDLE THIS ONE

anonymous · Answer

lol jk take it away !!

abb0t · Answer

Then, pick ANY point of the two, and plug it into: $\sf \color{Red}{(y-y_1)=m(x-x_1)}$
and rearrange it into the form: $\sf \color{purple}{y=mx+b}$

Im not good with algebra

abb0t · Answer

You are pluggig it in for $\sf \color{RED}{y_1 , x_1}$ NOT for y

abb0t · Answer

I already told you how to solve. I am not doing the work for you. Try it first. I told you step by step.
