The equation for the line that represents the data is y = 3.5x + 42.50.
The equation of a line is represented in the form y = mx + b. Where b is the y intercept and m is the slope of the line.
Calculating the slope;
m = 49.50 - 42.50 )/2-0
m = 7/2
m = 3.5
The equation of a line is derived from the equation
y -y₁= m(x-x₁)
y - 42.50 = 3.5(x - 0)
y - 42.50 = 3.5x
y = 3.5x + 42.50
Therefore, the equation for the line that represents the data is y = 3.5x + 42.50
