1. Identify the figure in which the line has a positive slope. 2. Find the x and y intercepts of the line 3x + 4y – 12 = 0

Question

Identify the figure in which the line has a positive slope. 

a. 

b.

c. 

d.

2. Find the x and y intercepts of the line 3x + 4y – 12 = 0

Answer 1

1. Figure b

2. 3x + 4y = 12

\(\Rightarrow \frac{3x + 4y}{12} = 1\)

\(\Rightarrow\) \(\frac{x}{4} + \frac{y}{3} = 1\)

x – intercept = 4; y – intercept = 3.
