help, I don't understand

Answer:
y=3/4x+10
Step-by-step explanation:
lts take two points
(-4,7)
(0,10)
so slope is 3/4
so 3/4*-4+b= 7
-3+b=7
b=10
y= 3/4x+10
if my answer helps please mark as brainliest.
Answer:
y = 3/4 x + 10
Step-by-step explanation:
the b is 10 because y is 10 when x is 0
to find the x, plug in any variable from the chart into the equation y=mx+b
i used (-4, 7), so the equation would be 7=m(-4)+10
solve for x
-4m=7-10=-3
m=3/4
