Question

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

Answer 1

• A(0, - 6) is the y-intercept

Explanation:

The y-intercept is the point where the graph intersects the y-axis.

It is a point with zero x-coordinate.

As we see the point A has x = 0, y = - 6 coordinates, it is therefore a y-intercept.

Answer 2

y = 2x - 6

Explanation:

given : A(0,-6) and B (7,8)

gradient = 8 - -6 / 7 -0

= 14/7

= 2

line : y - - 6 = 2 ( x - 0 )

: y + 6 = 2x

: y = 2x - 6
