Question

Write the equation of the linear relationship in slope-intercept form, using decimals as needed.

x 0 100 200 300
y 2.5 17.5 32.5 47.5


Enter the equation of the relationship.

y =

Answer 1

It’s not everything, but b=2.5 if that helps

Answer 2

Explanation:

we know that

The linear equation in slope intercept form is equal to

where

m is the slope

b is the y-intercept

Find the slope

The formula to calculate the slope between two points is equal to

take the points

(0,2.5) and (100,97.5)

substitute in the formula

Find the y-intercept b

we have

substitute i the linear equation

solve for b

Note It was not necessary to calculate the value of b because the value is given in the table

Remember that the y-intercept is the value of y when the value of x is equal to zero (the y-intercept is the point (0,2.5))

The linear equation is
