Problem: find the x and y intercepts of y=-4x+16
Find the intercepts of the graph of the equation y=-4x+16
The y-intercept is given in the equation: 16. This happens when
x is equal to zero.
To find the x-intercept, set y = 0 and solve.
y = -4x + 16
0 = -4x + 16
0 + 4x = -4x + 16 + 4x
4x = 16
4x/4 = 16/4
x = 4
The x-intercept is 4.
Answer: y-intercept is (0, 16); x-intercept is (4, 0)
