Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form. (2 points) a y = 3x − 7 b y = 3x
sashaice [31]

Answer: y = 5x − 11

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis represent

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

The line passes through (3,4) and (2, -1),

y2 = - 1

y1 = 4

x2 = 2

x1 = 3

Slope,m = (- 1 - 4)/(2 - 3) = - 5/- 1 = 5

To determine the y intercept, we would substitute x = 3, y = 4 and m= 5 into

y = mx + c. It becomes

4 = 5 × 3 + c

4 = 15 + c

c = 4 - 15 = - 11

The equation becomes

y = 5x - 11

tiny-mole [99]

Answer:

There are 650 cannonballs


Step-by-step explanation:

If you look closely in the picture, you can see that:

  • 1st row has 1 ball
  • 2nd row has 4 balls
  • 3rd row has 9 balls
  • 4th row has 16 balls

etc. etc.

We can see that the number of balls is the square of the row number. There are a total of 12 rows. So, rest of the rows has:

  • 5th row has 25 balls
  • 6th row has 36 balls
  • 7th row has 49 balls
  • 8th row has 64 balls
  • 9th row has 81 balls
  • 10th row has 100 balls
  • 11th row has 121 balls
  • 12th row has 144 balls

If we add up all those, we get total number of balls:

1+4+9+16+25=36+49+64+81+100+121+144=650

There are 650 cannonballs
