Question 942732: Hello! Here is the question I need help understanding:
"Write an equation for a linear function whose graph has the given characteristics: (-2,2)(2,-12)
I have tried m=y2-y1 over x2-x1, and I get -14/4 but that answer comes back incorrect. Please tell me what I'm doing wrong. Thank you so much
Answer by josgarithmetic(39618) (Show Source): You can put this solution on YOUR website!
You have the right idea.

Subscript 1, (-2,2);
Subscript 2, (2,-12);
.

Now, take your pick: Use either slope-intercept form or use point-slope form.

If slope-intercept,
y=mx+b, and you know m.
b=y-mx, and just pick either of the given points for x and y.
