Question

a line has a slope of 7 and a y-intercept of -1. write its equation in slope-intercept form.
write your answer using integers, proper fractions, and improper fractions in simplest form.

Explanation:

Step1: Recall slope-intercept formula

The slope-intercept form of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.

Step2: Substitute given values

Substitute $m = 7$ and $b = -1$ into the formula:
$y = 7x + (-1)$

Step3: Simplify the expression

Simplify the constant term:
$y = 7x - 1$

Answer:

$y = 7x - 1$
