Does the point (7, 4) satisfy the equation y = x − 3?

Yes.

Step-by-step explanation:

If we wrote the equation down

7=4-(-3)

Then, we do keep, change, change

7 = 4+3

Y = 7

The equation is true, so that means the points are.

what is the y-coordinate for A?

Step-by-step explanation:

Step-by-step explanation:

(14 - 8)/(7 - 4)= 6/3= 2

y - 8 = 2(x - 14)

y - 8 = 2x - 28

y = 2x - 20

Step-by-step explanation:

The equation of a circle of radius r, centered at the point (a,b) is

We already know the center is at , we are just missing the radius. To find the radius, we can use the fact that the circle passes through the point (7,4), and so the radius is just the distance from the center to this point (see attached image). So we find the distance by using distance formula between the points (7,4) and (4,-5):

radius

And now that we know the radius, we can write the equation of the circle:

C) (7 , 14)

Step-by-step explanation:

Substitute each ordered pair into the equation

-5x + 3y = 7.

A) (2 , -1)

-5(2) +3(1) = -10 +3 = -7  this does not equal 7  so not true

B) (-5 , 3)

-5(-5) +3(3) = 25 +9 = 34  this does not equal 7 so not true

C) (7 , 14)

-5(7) + 3(14) = -35 + 42 = 7  this equals 7 so true

D) (-2 ,−135)

-5(-2) + 3(-135) =10+405 =415  this does not equal 7 so not true

C) (7 , 14)

Step-by-step explanation:

Substitute each ordered pair into the equation

-5x + 3y = 7.

A) (2 , -1)

-5(2) +3(1) = -10 +3 = -7  this does not equal 7  so not true

B) (-5 , 3)

-5(-5) +3(3) = 25 +9 = 34  this does not equal 7 so not true

C) (7 , 14)

-5(7) + 3(14) = -35 + 42 = 7  this equals 7 so true

D) (-2 ,−135)

-5(-2) + 3(-135) =10+405 =415  this does not equal 7 so not true

B.
