Answer/Step-by-step explanation:
Shari's equation, 288x - 4y = -192, was stated in the standard form.
Thus, she thinks -192 was the y-intercept because:
She thought that the [constant term] is always the y-intercept. She forgot to [write the equation in slope-intercept form].
Let's find the correct y-intercept (b), by first rewriting the equation, 288x - 4y = -192, to get the equation in slope form, y = mx + b.
Thus:
288x - 4y = -192
-4y = -288x - 192 (subtraction property of equality)
y = -288x/-4 - 192/-4
y = 72x + 48
Thus, the y-intercept = b = 48
