What is the y-intercept of the equation 5x - 2y = 10?

5
-2
-5
2

The correct answer is: 2

The y-intercept of an equation represents the point where the line crosses the y-axis, which is when x is equal to 0. In order to find the y-intercept, one must substitute 0 for x and solve for y. In this equation, when x is 0, -2y = 10, which means that y = -5. Therefore, the y-intercept of this equation is -5. The other options may be tempting as they are all numbers that are included in the equation, but they do not represent the y-intercept as they do not have x equal to 0.
