Jackson pays $18 per month for his phone service, plus $0.07 for each long distance minute used. which of the following correctly describes the y-intercept?

y intercept is 18

Step-by-step explanation:

It is given that

Monthly rent for phone service = $18

charges for each long distance minute = $ 0.07

Let us assume number of minutes used = x

also let us represent total cost by  y

So the total cost = ( charges per minute )(number of minutes) + monthly rent

now we compare this equation with y=mx+b

where m is the slope and b is y intercept

so we have b= 18

hence y intercept is 18

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

2,600 divided by 80 = 32.5
