A line has a slope of _3 and a y-intercept of 3.
What is the x-intercept of the line?

To find the x-intercept of that line, we have to make that information to equation. Withe that information, we can make the slope-intercept form which is y = mx+ b.

To put that information into that form, we can get

y = -3x + 3

To find the x-intercept, we have to set y = 0 and solve the equation

0 = -3x + 3

0 - 3 = -3x + 3 - 3

-3 = -3x

-3 / -3 = -3x/-3

So the answer is 1
