Question

dry cleaning bill is shown by y equals 1.50 x + 4.50 y is the total cost and x is the number of shirts graph this equation​

Answer 1

The graph in the attached figure

Explanation:

Let

y------> the total cost

x------> the number of shirts

we know that

The linear equation is

`y=1.50x+4.50` ------> equation of the line

To graph the line find the intercepts

The y-intercept is the value of y when the value of x is equal to zero

The x-intercept is the value of x when the value of y is equal to zero

Find the y-intercept

For x=0

`y=1.50(0)+4.50=4.50`

The y-intercept is the point (0,4.50)

Find the x-intercept

For y=0

`0=1.50x+4.50`

`1.50x=-4.50`

`x=-4.50/1.50=-3`

The x-intercept is the point (-3,0)

Plot the intercepts to graph the line

see the attached figure
