Answer: y=-3x-15

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" the y-intercept.

Since the given line  has a y-intercept at (0,-15), then:

b=-15

The formula for calculate the slope is:

m=\frac{y_2-y_1}{x_2-x_1}

Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:

 m=\frac{-15-(-3)}{0-(-4)}=-3

Substituting values into y=mx+b, we get that the equation of the line in Slope-Intercept form is:

y=-3x-15

hey, do any of you guys know how to plot functions on a graph. You know like f(X) and g(X)? I find it really hard and also do yo
Tpy6a [65]
It helps if you have an example, like f(x) = 2x+3
What you typically do, is:

- draw xy axis, label them (ie., 1,2,3,4 along both axes)
- calculate the f(x) values for several x (e.g., -2, 0, 1, 3, doesn't matter).
- plot the calculated values as points. The calculated f(x) is your y value.
- sketch a smooth line through the points. It helps if you know in advance if the line is going to be straight or curved. 
- The more points you calculate, the more accurate your graph will be

Adriano wants to get a new cell phone plan. Company A: $80 for a new phone in the monthly fee of $45 a month. Company B: she can
Degger [83]

Answer: it will take 2 months.

Step-by-step explanation:

Let x represent the number of months it will take for the total cost for both companies to be equal.

Company A: $80 for a new phone and the monthly fee of $45 a month. This means that the total amount that Company A charges for x months would be

80 + 45x

Company B: she can keep her all sound and pay $85 a month. This means that the total amount that Company B charges for x months would be

85x

For the total cost for both companies to be equal, the number of months would be

80 + 45x = 85x

85x - 45x = 80

40x = 80

x = 80/40 = 2
