Question

Y intersect of a graph showing the points A(0,-6) and B (7,8)

Answer 1

• 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

Answer 2

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
