Answer:
54: slope = m = -1/5
y-intercept = b = -6
55. -3x + 12
Step-by-step explanation:
Note the equation formula:
y = mx + b
Note that:
m = slope
b = y-intercept
x & y = (x , y)
Note the equation:
y = (-1/5)x - 6
slope = m = -1/5
y-intercept = b = -6
Simplify the expression:
-3(x - 4)
To solve, distribute -3 to all terms within the parenthesis. Multiply:
(-3) * (x) = -3x
(-3) * (-4) = 12
-3x + 12 is your answer.
