Question

20x+2y=9 what is the y intercept

Answer 1

20x + 2y = 9

We want to write the given equation in the form y = mx + b, where b is the y-intercept.

Subtract 20x from both sides.

2y = -20x + 9

Divide both sides by the coefficient of y.

2y/2 = (-20x + 9)/2

y = -10x + 9/2.

The y-intercept is 9/2.

We can also write the y-intercept as a point in the form (0, 9/2).

Answer 2

The y intercept is (0,9/2)

Explanation:

There are multiple ways of solving this question one way is substituting x for 0.

20(0)+2y=9

0+2y=9

y=9/2

(0,9/2)
