Answer:  y = \frac{1}{2}x+3

This is the same as writing y = (1/2)x + 3

========================================================

Explanation:

Two points on the blue line are (0,3) and (2,4)

To go from the left point to the right, we go up 1 and over to the right 2.

Slope = rise/run = 1/2

Or we can use the slope formula to get the same value

m = (y2-y1)/(x2-x1)

m = (4-3)/(2-0)

m = 1/2

The y intercept is b = 3 because this is the location on the vertical y axis where the blue line crosses. This is the location (0,3).

With m = 1/2 and b = 3, we go from y = mx+b to y = (1/2)x + 3

On a piece of paper, that would look like the equation y = \frac{1}{2}x + 3

The diameter of a circle has endpoints P(-12, -4) and Q(6, 12).
nexus9112 [7]

9514 1404 393

Answer:

  (x +3)² +(y -4)² = 145

Step-by-step explanation:

The center of the circle is the midpoint of the given segment PQ. If we call that point A, then ...

  A = (P +Q)/2

  A = ((-12, -4) +(6, 12))/2 = (-12+6, -4+12)/2 = (-6, 8)/2

  A = (-3, 4)

The equation of the circle for some radius r is ...

  (x -(-3))² +(y -4)² = r² . . . . . . where (-3, 4) is the center of the circle

The value of r² can be found by substituting either of the points on the circle. If we use Q, then we have ...

  (6 +3)² +(12 -4)² = r² = 9² +8²

  r² = 81 +64 = 145

Then the equation of the circle is ...

  (x +3)² +(y -4)² = 145

Is the ordered pair (0, 4) a solution of the inequality y≤x−3? Explain.
Andrew [12]

The ordered pair (0,4) does not satisfy the inequality thus, it will be not the solution to the given inequality.

<h3>What is inequality?</h3>

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given inequality,

y ≤ x - 3

Put x = 0

y ≤ 0 - 3

y ≤ -3

Since 4 ≤ -3 is the wrong statement thus it will not satisfy the inequality.

Hence "The ordered pair (0,4) does not satisfy the inequality thus, it will be not the solution to the given inequality".
