Question

How do you find the intercepts for `-7x + 2y = 14`?

Answer 1

y-intercept = 7, x-intercept = -2

Explanation:

y-intercept is the point on the graph of y against x where x = 0. Substituting x = 0 gives 2y = 14, y = 7.

Similarly for the x-intercept, the y-coordinate must be 0. Substituting y = 0 gives -7x = 14, x = -2.
