Question

Write the equation of the linear relationship in slope Intercept form, using decimals as needed. 0 2.5 100 200 300 375 725 1075 Enter the equation of the relationship.

Answer 1

Let us first calculate the slope of the function. We need 2 points (0,2.5) and (100,37.5)

so the slope is

$m=\frac{37.5-2.5}{100-0}=\frac{35}{100}=\frac{7}{20}=0.35$

So the equation is

$y=0.35x+2.5$
