Chapter 2: Q18. (page 78)

State the slope and y-intercept of the graph of each equation.
$cx + y = d$

Short Answer

Expert verified

The slope of the given line is $- c$ and the y-intercept of the given line is $d$ .

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 $c x + y = d$ .

– Identify the slope and intercept

Convert the given equation to slope-intercept

form as follows:

$c x + y = d$ (Given equation)

$c x + y - c x = d - c x$ (Subtract $c x$ from both sides)

$y = d - c x$ (Simplify)

$y = - c x + d$ (Rearrange)

So, the given equation in slope-intercept form is $y = - c x + d$ .

Comparing the obtained equation,

$y = - c x + d$ with $y = m x + c$ , $m = - c$ and $c = d$ .

This implies that the slope of the given line is $- c$ and the y-intercept of the given line is $d$ .
