Question

Use this new algebraic method to find equations for the line with the following properties:
A slope of −3, passing through the point (15,−50).
Show your work in the sketch box on the left.
Step 1: Substitute values for m, x, and y.
Step 2: Solve equation for b.
Step 3: Rewrite your equation with only m and b.
What is the equation of this line?

Answer 1

Answer:

Y = -3x + 90

Step-by-step explanation:

Y= Mx + b

M - (-3)

X - 15

Y - (-50)

Y = Mx + b

50 = (-3)(15) + b

50 = -45 + b

95 = b

Y = -3x + 90
