Find the Slope and y-intercept D(r)=23/20r+3/4

$D (r) = \frac{23}{20} r + \frac{3}{4}$

Step 1

Rewrite in slope-intercept form.

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Simplify the right side.

Combine $\frac{23}{20}$ and $r$ .

$y = \frac{23 r}{20} + \frac{3}{4}$

Rewrite in slope-intercept form.

$y = \frac{23}{20} r + \frac{3}{4}$

Step 2

Use the slope-intercept form to find the slope and y-intercept.

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = \frac{23}{20}$

$b = \frac{3}{4}$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $\frac{23}{20}$

y-intercept: $(0, \frac{3}{4})$

Slope: $\frac{23}{20}$

y-intercept: $(0, \frac{3}{4})$
