What is the y-intercept of y equals 2x plus 10?

Answer 1

The y-intercept means... When does the line cross through the y-axis?

This happens when the x-value is zero... so simply just plug in zero for "x"

y = 2 * (0) + 10

y = 10

y-intercept is equal to 10

For the x-intercept just make the y-value equal to zero.
