Question

Consider the equation 1.5x+4.5y=18 if we graph the equation what is the slope of the graph

Answer 1

slope = -1/3

Explanation:

put into for y=mx +b

1.5x + 4.5y = 18

4.5y = -1.5x + 18

y = (-1.5/4.5)y + (18/4.5)

simplify

y = (-1/3)y + (16/9)

y=mx+b

m = slope

b = y-intercept

slope = -1/3
