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-axis?

Answer 1

9

Explanation:

To find the value of y at the point where the line crosses the y-axis, we set x = 0 and solve for y in the given equation.

Substituting x = 0 into the equation, we have:

y + 4 = 6(0) + 13

Simplifying the equation further:

y + 4 = 0 + 13

y + 4 = 13

To isolate y, we subtract 4 from both sides:

y = 13 - 4

y = 9

Therefore, the value of y at the point where the line crosses the y-axis is 9.
