Answer:
y-intercept: (0,3); x-intercept: (12,0)
Step-by-step explanation:
The y-intercept is in a line where x = 0, so to find it, you can plug in 0 for x in the equation.
y = -¹/₄(0) + 3
y = 0 + 3
y = 3
So when x = 0, y = 3, therefore the y-intercept is (0,3)
The x-intercept is when y = 0, so plug in 0 into y
0 = -¹/₄x + 3
-3 = -¹/₄x
x = 12
So when = 0, x = 12, therefore the x-intercept is (12,0)
Answer:
(0,3)
Step-by-step explanation:
y = -1/4 + 3
The intercept is (0,3)
