The straight line is given by the equation
y=kx+b
We substitute coordinates of points
3=2k+b (1)
9=4k+b (2)
We give a system of equations
Solution of this system
(1) 2k=3-b
k=(3-b)/2
(2) 9=2(3-b)+b
9=6-b
b=-3
k=3
Answer: y=3x-3
Distribute -3 to the rest of the numbers by multiplying them together. That’s all you need to do you don’t have to solve
