Answer
$y$-intercept is $3$.
The slope is $m=2$.
Refer to the graph below.
Work Step by Step
In a line's equation in slope-intercept form, which is $y=mx+b$, the constant $b$ is the $y$-intercept while the coefficient of $x$, which is $m$, is the slope.
Thus, in $y=2x+3$ we have:
$y$-intercept is $3$
slope=$m=2$.
Plot the point $(0, 3)$.
The slope is $2$ so from $(0, 3)$, move $1$ unit to the right and $2$ units upward to have $(1, 5)$.
Connect the points using a straight line.
