The table below shows the relationship between the number of hours a computer programming project takes and the cost charged by a programmer. hours(x) 4 6 8 10 cost(y) $725 $975 $1225 $1475 write a linear equation in slope- intercept form that describes the relationship form that describes the relationship in terms of x and y. how much does the programmer charger per hour? how much does the programmer charge for a 25-hour long project?

y = 125x+225

The programmer chargers a flat fee of 225 and then $125 per hour.

The charge for a 25 hour project is $3350

Step-by-step explanation:

To find the slope  (y2-y1)/(x2-x1)

          m = (1475-725)/(10-4)

             = 750/6

             =125

The slope is $125

Using the point slope form of the equation for a line

y-y1 = m(x-x1)

y-725 = 125(x-4)

Distribute the 125

y-725 =125x-500

Add 725 to each side

y-725+725 = 125x-500+725

y = 125x+225

The programmer chargers a flat fee of 225 and then $125 per hour.

If you have a 25 hour long project, let x =25

y = 125(25) + 225

y= 3125+225

y = 3350
