Hi Kayla D.
Given m= 3/4; y intercept (0,4)
Slope intercept form is
y = mx + b
m = 3/4
y intercept is always (0,b), so b= 4
You can also solve to show this please see below
You can use the (x,y) coordinates you are given to solve for b, use (0,4)
4 = (3/4)(0) + b
4 = 0 + b
4 = b
Line in slope intercept form is
y = (3/4)x + 4
You can graph your line at desmos.com.
You can look up Slope Intercept Form
y = mx + b
y intercept is always (0,b)
In your problem you are given both m and b.
I hope this helps
