How do you graph y=1/2x +4?

$\left(4 , 0\right)$ then a second point is at $\left(5 , 2\right)$

Explanation:

$y = m x + b$

$m$ = slope
$b$ = y-intercept (where the line crosses the x-axis)

go up to $4$ on the $y$ axis (4,0). That is one of the points. From that point, which is $\left(4 , 0\right)$, use the slope and graph the next point, so the slope is $m$, which is $\frac{1}{2}$. The numerator ("$1$") states how much you go up or down (positive (+) up, negative (-) down). so in this case, you go up one on the y-axis. Then from that point go $2$ points to the right (you get this from the denominator of $\frac{1}{2}$) if there is no denominator (ex: y=5x+1), there is always a $1$ underneath every number ($y = \frac{5}{1} x + 1$).
