-59.744
That’s when you solve for x and y in the equation x= 3/4 and y=-9/7
Tan inverse of y/x gives u -59.744

Write an equation of a line that passes through the given point and has slope m (3,4) m=1/2

yanalaym [24]

Plug the point and the slope into point-slope form and simplify to get it in slope-intercept form.

$\sf~y-y_1=m(x-x_1)$

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

$\sf~y-4=\dfrac{1}{2}(x-3)$

Distribute 1/2:

$\sf~y-4=\dfrac{1}{2}x-1.5$

Add 4 to both sides:

$\boxed{\sf~y=\dfrac{1}{2}x+2.5}$

or

$\boxed{\sf~y=\dfrac{1}{2}x+2\dfrac{1}{2}}$

Faye pays her family phone bill, and Jonathan’s family phone bill with her card and jonathan pays her back. If Faye bill is $120

nika2105 [10]

Answer:

Jonathan has to pay Faye back US$ 240

Jonathan has 4 people on his bill and Faye has 6.

Step-by-step explanation:

1. Let's find out the amount of the phone bills, this way:

Total of the two bills = US$ 600

Faye's bill = US$ 120 more than Jonathan's

Jonathan's bill = x

Solving for x, we can use this equation:

x + x + 120 = 600

2x + 120 = 600

2x = 600 - 120

2x = 480

x = 480/2 = 240

Jonathan has to pay Faye back US$ 240

2. Let's find out the number of people on each bill, this way:

Faye has two people more on her bill than Jonathan

Number of people on Jonathan's bill = x

Number of people on Faye's bill = x + 2

We will use the following equation:

240 * (x + 2) = 360x

240x + 480 = 360x

240x - 360x = -480

-120x = - 480

x = -480/-120

x = 4 ⇒ x + 2 = 6

Jonathan has 4 people on his bill and Faye has 6.
