We know the equation has to be in the form y=mx+c

12--6/10-4
=18/6
=3 (this 3 is our m value)
now we know the gradient we can substitute in one of the points

y=3x+c
12=(3×10)+c
12=30+c
-18=c

therefore the equation of line is y=3x-18

the equation for finding the slope of a line is [tex] \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }} [/tex] .


Inserting the points, we get [tex] \frac{ -6 - 12 }{ 4 - 10 }} [/tex]  which is 6 / 6 or 1.
