Chapter 4: Q. 387 (page 537)

In the following exercises, find the equation of a line with a given slope and $y$ -intercept. Write the equation in slope-intercept form.
$387 .$ slope $4$ and $y$ -intercept $(0, 1)$

Short Answer

Expert verified

The equation of the line with the given slope $4$ and $y$ -intercept $(0, 1)$ is $y = 4 x + 1$ .

Step by step solution

Step 1. Given data

We have to find the equation of the line.

For that we have,

Slope $(m) = 4$

$y$ -intercept $= (0, 1)$

Step 2. Equation of the line

We have the point-slope formula $y - y_{1} = m (x - x_{1})$

Where $m$ is the slope and $(x_{1}, y_{1})$ is a point through which the line passes.

Here,

$m = 4 (x_{1}, y_{1}) = (0, 1)$

Let us substitute these in the point-slope formula,

That is,

localid="1647282602319" $\begin{aligned} y - 1 = 4 (x - 0) \\ y - 1 = 4 x \\ y = 4 x + 1 \end{aligned}$

Hence $y = 4 x + 1$ is the equation of the line with slope $4$ and $y$ -intercept $(0, 1)$ .
