----------------- = --------------- Divide the top and bottom
8 towels 1 towel of this proportion by 8.
15/8 = 1.88
8/8 = 1
Answer:
y = 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 ← is in slope- intercept form
with m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation
To find c substitute (4, 5) into the partial equation
5 = 12 + c ⇒ c = 5 - 12 = - 7
y = 3x - 7 ← equation of line
