Question

Lana graphs the equation x + 3y = −6 as shown. Identify the error on the graph

Answer 1

Answer:

D

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 )

Given

x + 3y = - 6 ( subtract x from both sides )

3y = - x - 6 ( divide all terms by 3 )

y = - $\frac{1}{3}$ x - 2 ← in slope- intercept form

with slope m = - $\frac{1}{3}$ and y- intercept c = - 2

Answer 2

D) the slope of the line on the graph is -2/3
