Question

Find the equation in standard form which passes through (–2, –7) and (1, –1). You must show all work.

Answer 1

\[m=\left( y _{2}-y _{1} \right)\div \left( x _{2}-x _{1} \right)\]=2
y=mx+c (assuming you're asking for a straight line) so y=2x+c subbing in the point (1,-1) gives c=-3
so y=2x-3

Answer 2
