PLEASE HELP ME Determine the equation of the line if you have a slope of -2 and a point E (1,1)

A y = -2x + 3

B y = 2x + 3

C. y = -3x + 2

D. y = 3x - 2

A is the correct answer

Step-by-step explanation:

The y intercept is at three when you go down 2 and to the right 1

you get the point (1,1)

A (-2x+3)

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx+b. M being the slope and b being the y-intercept. We know the slope is -2, so we have y = -2x+b. If point E is at (1,1), we can use that to get our y-intercept (where x=0). That point would be (0,3) since a negative slope increases the farther left along the x-axis you go and has an absolute value of 2, thereby increasing by 2 for every 1 travelled along the x-axis. (0,3) is the y-intercept thus we get y = -2x+3.

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
