Chapter 3: Q. 108 (page 276)

Identify the slope and y-intercept of each line.
$7 x - 3 y = 9$ .

Short Answer

Expert verified

Slope of the line is $\frac{7}{3}$ and y-intercept is $(0, - 3)$ .

Step by step solution

Step 1. Given information

Given equation of the line is $7 x - 3 y = 9$ .

Step 2. Finding the slope and y-intercept.

Solving the given equation for y, we get

$\Rightarrow 3 y = 7 x - 9 \Rightarrow y = \frac{7 x - 9}{3} \Rightarrow y = \frac{7 x}{3} - \frac{9}{3} \Rightarrow y = \frac{7}{3} x - 3$

Now comparing with slope-intercept form of the line $y = m x + b$ , we get

$m = \frac{7}{3}$ and $b = - 3$ .

Therefore slope of the line is $\frac{7}{3}$ and y-intercept is $(0, - 3)$ .
