FIRST
Write the two points that pass through the graph
(x₁,y₁) = (0,0)
(x₂,y₂) = (2,94)
SECOND
Find the slope of the line first
m = (y₂ - y₁)/(x₂ - x₁)
m = (94 - 0)/(2 - 0)
m = 94/2
m = 47
You can make algebraic expression with the help of line equation formula
y - y₁ = m(x - x₁)
Now input the numbers to the formula
y - y₁ = m(x - x₁)
y - 0 = 47(x - 0)
y = 47x
The answer is third option
