Question

anonymous · Answer

Part b.) Using the slope that you found in part a and one of the given points, write the equation of the line. Please write your final answer in slope-intercept form.

slope = y2 - y1
            ------
            x2 - x1

anonymous · Answer

To find slope, use the equation x_2-x_1 over y_2-y_1 so we'll come up with 3 for slope

saifoo.khan · Answer

insert it.

anonymous · Answer

Err.. other way around for my answer

Saifoo got creative :D

YAY! :D

SO HOW  do u do part b??

anonymous · Answer

Slope intercept form is y=mx+b so insert slope to m and any two points to solve for b

anonymous · Answer

ok thanks

anonymous · Answer

so i can say y=3x+5??

anonymous · Answer

We'll use (1,2) and come up with 2=3(1)+b  so after solving for b we get b=-1 so take that and plug it into y=mx+b you come up with y=3x-1
