Graph by using the slope and the y intercept.

Answers

1. a) equation of the line :

[tex]y = \dfrac{2}{5}x - 7[/tex]

y - intercept = -7

so, it will pass through point (0, -7)

and if we plug the value of x as 5, we get

[tex]y = (\dfrac{2}{5} \times 5) - 7[/tex]

[tex]y = 2 - 7[/tex]

[tex] = - 5[/tex]

so, it will pass through point (5, -5) too

now, just plot the points (0 , -7) and (5 , -5) and join them.

2. b) equation of line is :

[tex]y = - 3x + 5[/tex]

here, y - intercept = 5

so the line passes through point (0 , 5)

now, Plugging the value of x = 1 we get :

[tex]y =( - 3 \times 1) + 5[/tex]

[tex]y = - 3 + 5[/tex]

[tex]y = 2[/tex]

so, the given line passes through point (1 , 2)

plotting the points, we can get our required line.

Answer:

Pizza 1: lenght(l)=16 and width(w)=4

Perimeter=40in.

Pizza 2: l=32 and w=2

Perimeter=68in.

Step-by-step explanation:

1. List down factors of 64.

64=1,2,4,8,16,32,64

2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.

3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.

4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)

Pizza 1: Perimeter=2(16+4)

=2×20

=40in.

Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.
