y=2x+10 if I graphed correctly!

y=mx+b m=slope b=y intercept first find slope the sloe of the line that passes through the points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1) so the slope of the line that passes through the points (-2,6) and (2,14) is (14-6)/(2-(-2))=(8)/(2+2)=8/4=2 slope is 2 y=2x+b find b by subsituting a point (2,14) x=2 and y=14 14=2(2)+b 14=4+b minus 4 both sides 10=b so the equation is y=2x+10
