can someone help me please

The equation of a line is y = 50x. Then the slope of the line is 50 meters per minute.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Jenna can swim 150 meters in 3 minutes.

If you graph this with minutes on the X-axis and meters on the Y-axis.

Then the slope of the line will be

m = 150 / 3

m = 50 mters per minute

Then the equation will be

y = 50x

Answer:

70, 75, 80, 85

Step-by-step explanation:

1- 100/50=2•35=70

2- 100/100=1•75=75

3- 100/60=7/6•48=80

4- 100/20=5•17=85

Answer:

I am pretty sure B is correct answer

Answer:

A. Slope is -5. Y-intercept is (0,7)

Step-by-step explanation:

1. Find the slope using the slope formula and the coordinates

Remember, the slope formula is: y2-y1/x2-x1

You'll use the coordinates (0,7) (4, -13) to plug into the formula.

-13-7/4-0

= -20/4

= -5

Slope is -5

2. Find the y-intercept.

First, write the equation of the line in point-slope form: y-y1=m(x-x1)

M is slope and y1 and x1 can be from any ordered pair (as long as they're from the same one). Let's use (0,7)

y-7=-5(x-0)

Simplify the equation.

y-7=-5x+0

y=-5x+7

3. Now the equation is in y-intercept form, or y=mx+b. Again, M is slope. B is the y intercept. So, the y-intercept is 7

Answer:

8 and 64

Step-by-step explanation:

4/1 = 4

8/2 = 4

32/8 = 4

64/16 = 4

Answer:

1:4

2:8

8:32

16:64

Step-by-step explanation:

The constant of proportionality is 1:4. Whatever number is on the right has to  be 4 times greater than the number on the left for it to be proportional. I divided 32 by 4 to get 8 on the first one, and I multiplied 16 by 4 on the second one to get 64.

Step-by-step explanation:

The quotient of given numbers is 6.4.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, dividend =70.4 and divisor=11.

The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.

Here, 70.4/11

= 6.4

Therefore, the quotient is 6.4.
