Q16. State the slope and y-intercept ... [FREE SOLUTION]

Chapter 2: Q16. (page 78)

State the slope and y-intercept of the graph of each equation.
$3 x + 5 y - 30 = 0$

Short Answer

Expert verified

The slope of the given line is $- \frac{3}{5}$ and the y-intercept of the given line is 6.

Step by step solution

– State the concept

The general equation of a straight line in slope-intercept form is given as $y = m x + c$ , where $m$ is the slope and $c$ is the y-intercept.

– List the given data

The given equation of the line is $3 x + 5 y - 30 = 0$ .

– Identify the slope and intercept

Convert the given equation to slope-intercept form as follows:

$3 x + 5 y - 30 = 0$ (Given equation)

$3 x + 5 y - 30 - 5 y = 0 - 5 y$ (Subtract $5 y$ from both sides)

$3 x - 30 = - 5 y$ (Simplify)

$- 5 y = 3 x - 30$ (Rearrange)

$\frac{- 5 y}{- 5} = \frac{3 x - 30}{- 5}$ (Divide both sides by -5)

$y = - \frac{3}{5} x + 6$ (Simplify)

So, the given equation in slope-intercept form is $y = - \frac{3}{5} x + 6$ .

Comparing the obtained equation, $y = - \frac{3}{5} x + 6$ with $y = m x + c$ , $m = - \frac{3}{5}$ and $c = 6$ .

This implies that the slope of the given line is $- \frac{3}{5}$ and the y-intercept of the given line is 6.
