Question

In the xy- plane, the graph of the equation y + 3x + 5 is a line that intersects the y-axis at (0,b) what is the value of b?

Answer 1

`b=5`

Explanation:

The given equation is:

`y=3x+5`

To find the point where this line intersect the y-axis, we put x=0 into the given equation.

When x=0, we have
`y=3(0)+5`.

This implies that; y=5.

The y-intercept is (0,5).

Comparing (0,5) to (0,b), we can conclude that; b=5
