Answer:

  y = 5x -2

Step-by-step explanation:

The slope is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (8 -3)/(2 -1) = 5

The y-intercept is given by the formula:

  b = y -mx

  b = 3 -5(1) = -2

Then the slope-intercept form equation is ...

  y = mx +b

  y = 5x -2 . . . . . . . . using the m and b we found above

Round the decimal to the nearest hundredths 983.625
r-ruslan [8.4K]
983.625
9 = hundreds
8 = tens
3 = ones
6 = tenths
2 = hundredths
5 = thousandths
You want to round to the nearest hundredths
Look at the number on the right, if it's bigger than 5, round up, if it's 4 or lower, round down.
In this case, the number to the right is a 5, so you round the 2 (hundredths) up one so:

A square pyramid is shown below: What is the surface area of the pyramid?
Reptile [31]
Well first you would find the area of the square on the bottom
Which would be:
            0.7*0.7= .49
Then we would find the area of one of the triangles on the side:
           8*0.7= 5.6* 1/2= 2.8
Next, you will multiply the 2.8 by 4, because there are 4 triangles:
          2.8*4=11.2
Finally add the 11.2 to the area of the square, and you'll have your answer.
          .49+11.2= 11.69
So, B is your answer

Hey there I need some assistance need on this problem. What do I mean by checkpoints and how am I supposed to find the y-interce
MakcuM [25]

Slope Formula: y2 - y1 / x2 - x1

(m and slope represent the same quantity)

m = 1 - - 5 / -4 - 0

m = 1 + 5 / -4

m = 6 / -4

m = -3/2

Now that we know the slope, we can plug the slope and one of our points into slope-intercept form (y = mx + b) and solve for b. I will be using the point (-4,1).

y = -3/2x + b

1 = -3/2(-4) + b

1 = 6 + b

b = -5

In point form, the y-intercept is (0, -5).

Therefore, to get the equation all we need to do is plug in our slope and b-value to slope-intercept form.

Equation: y = -3/2 x - 5

To check the point (-6, -14) we plug it into our equation and see if the two sides are equal.

-14 = -3/2(-6) - 5

-14 = 9 - 5

-14 = 4

-14 does not equal 4, therefore the point is NOT on the line.

Hope this helps!

A baseball team played 177 complete games last season. They had 33 fewer wins than losses. How many games did the team win
NISA [10]
72 I believe because you have to subtract the 33 from the number of total games & then divide by two because you already took out the 33 more loses than wins.
