Find the Slope and y-intercept w(t)=40+90t

$w (t) = 40 + 90 t$

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.

$y = m x + b$

Reorder $40$ and $90 t$ .

$y = 90 t + 40$

Step 2

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

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

$m = 90$

$b = 40$

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

Slope: $90$

y-intercept: $(0, 40)$

Slope: $90$

y-intercept: $(0, 40)$
