Chapter 4: Q. 303 (page 520)

In the following exercises, identify the slope and y-intercept of each line.
$7 x - 3 y = 9$

Short Answer

Expert verified

Required slope is $\frac{7}{3}$ and y-intercept is -3.

Step by step solution

Step 1. Given information.

The equation $7 x - 3 y = 9$ .

Step 2. Solve the given equation for y.

Solve the equation $5 x - 2 y = 6$ for y:

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

Step 3. Compare the obtained equation with slope-intercept form of equation.

Compare the obtained equation $y = \frac{7}{3} x - 3$ with $y = m x + b$ .

$m = \frac{7}{3}; b = - 3$

So, slope is $\frac{7}{3}$ and y-intercept is $- 3$ .
