Answer:

x-y=5

Step-by-step explanation:

If a line has a slope of 1, its function can be write as x-y=c

insert point (7,2),t then we can find out the constant c=5, so the equation of this line is x-y=5

Answer:

The equation of the line is: y = 0.6x + 0.6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Two points:

We have these following two points in this exercise:

x = -6, y = -3, so (-6,-3)

x = 4, y = 3, so (4,3)

Finding the slope:

Given two points, the slope is given by the change in y divided by the change in x.

Change in y: 3 - (-3) = 3 + 3 = 6

Change in x: 4 - (-6) = 4 + 6 = 10

So

m = \frac{6}{10} = 0.6

Then

y = 0.6x + b

Finding b:

We replace one of the points in the equation to find b. I will use (4,3).

y = 0.6x + b

3 = 0.6*4 + b

2.4 + b = 3

b = 0.6

The equation of the line is: y = 0.6x + 0.6

Let Pencils be P

Let notebooks be N

Let graph paper be G

Let cost be C

(Always write a let statement before you write and algebraic equation)

C= (Px0.25)+(Nx1.75)+(Gx0.05)
