Step-by-step explanation:
Remark
The gradient is the same thing as m in y = mx + b. The point is used to find b.
Step One
Find the gradient and put it in the right place for y = mx + b
m = 2
y = mx + b
y = 2x + b So far this is the answer. Now we go on
Step Two
Use the point to find b
y = 4
x = 1
y = 2x + b
4 = 2*1 + b
b = 4-2
b = 2
Answer
y = 2x + 2
