What is the (y)-intercept of the equation (5y=20x-35)?
Advertisement
Answer and explanation
Correct answer: -7
Dividing 5y = 20x - 35 by 5 gives y = 4x - 7. In the form y = mx + c, the constant c is the y-intercept, so the y-intercept is -7. Here, 4 is the slope, not the y-intercept. Exam tip: You can also find the y-intercept by putting x = 0.
