Question

If you graph 2y+8=6x^2-10x what will be the y intercept?

Answer 1

Y intercept will be -4.

Explanation:

Here we are given our function as

`2y+8=6x^2-10x`

We are asked to determine the y intercept.

The y intercept is the y ordinate of the coordinates of the point at which the graph of the function intersects the y axis.

Please note that the point at which graph cuts the y axis have x=0

Hence in order to determine y intercept we need to put x=0 in our function and solve it for y :

`2y+8=6x^2-10x2y+8=6x^2-10x`

Putting x =0

`2y+8=6x^2-10x2y+8=6(0)^2-10(0)`

`2y+8=6x^2-10x2y+8=0-10(0)`

`2y+8=6x^2-10x2y+8=0`

subtracting both sides by 8

`2y+8=6x^2-10x2y=-8`

dividing both sides by 2

=-4
