Question

the equation of a line is y + 4 =6x + 13. what is the value of y at the point where the line crosses the y-xais?

Answer 1

y = 9

Explanation:

When a line crosses the y-axis, it crosses at point (0,y).

Substitute x = 0 in to the line equation we get:

y + 4 = 0 + 13

So y = 13 - 4 = 9

The line crosses the y-axis at point (0,9)
