Question

At what point does the line given by the following equation cross the y-axis?

y = 6/9x+3

a. (0,3)

b. (3,0)

c. (0,-)

d. (-9/2,0)

Answer 1

A

Explanation:

In a slope-intercept equation, the format goes like this:

• y = mx + b

M = Slope

B = Y-intercept

In the equation, y = 6/9x + 3:

The slope is 6/9

The y-intercept is 3.

So what the question means by "cross the y-axis" is when the line on the graph is going through the y-intercept point.

Because the y-intercept is 3, the ordered pair would look like this:

(0, 3)

Note: The y-intercept is when the x-intercept has a value of 0 and the y-intercept is only on the y-axis, never the x-axis.

Therefore, the answer would be Option A. (0, 3)
