  • A(0,-6)
  • B(7,8)

Slope:-


\\ \rm\rightarrowtail m=(8+6)/(7-0)=(14)/(7)


\\ \rm\rightarrowtail m=2

Equation in point slope form


\\ \rm\rightarrowtail y+6=2(x)


\\ \rm\rightarrowtail y=2x-6

  • Y intercept=-6

Explanation:

Slope of the line:


m = (8 + 6)/(7) = 2

know that:


y - y 0 = m(x - x0)

Using m=2 and A(0, —6):


y + 6 = 2(x) \\ y = 2x - 6

So y-intercept is —6
