What is the equation of this graphed line? enter your answer in slope-intercept form in the box. need due today

Step-by-step explanation:

step 1

Find the slope

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

we have

Substitute the values

step 2

we know that

The equation of the line into slope intercept form is equal to

we have

substitute and solve for b

------>

The equation of the line is equal to

what

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
