Full solution

Q. Find the equation of a line whose slope is

-4 / 5

and whose

y

-intercept is

(0,7)

.

\newline

\square

Definition of Slope-intercept form: Slope-intercept form is $y = mx + b$ , where $m$ is the slope and $b$ is the $y$ -intercept.
Given values for slope and y-intercept: We have the slope $m$ as $-\frac{4}{5}$ and the y-intercept $b$ as $7$ .
Substitute values into equation: Substitute $-\frac{4}{5}$ for $m$ and $7$ for $b$ into the slope-intercept form equation. $\newline$ $y = \left(-\frac{4}{5}\right)x + 7$
