Question

a line has a slope of 1 and a y-intercept of 4. 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 $m=1$ and $b=4$ into the formula:
$y = 1x + 4$

Step3: Simplify the expression

Since $1x$ is equivalent to $x$, simplify the equation:
$y = x + 4$

Answer:

$y = x + 4$
