Answer:

  d)  (x -2)² +(y +5)² = 256

Step-by-step explanation:

For center (h, k) and radius r, the standard equation of a circle is ...

  (x -h)² +(y -k)² = r²

For (h, k) = (2, -5) and r = 16, we can fill in the numbers:

  (x -2)² +(y -(-5))² = 16²

  (x -2)² +(y +5)² = 256 . . . . simplify

Which equation represents a line parallel to the line shown on the graph?
Delicious77 [7]

The  equation y=2x+1 has the same slope , so will be parallel to the given line.

<h3>What is a linear function ?</h3>

A function that can be represented in the form of y =mx +c , is called a Linear Function.

here m is the slope and c is the y intercept.

The slope of the given line can be found as follows

The y intercept is 4

at x = -2 , y =0

0 = -2m + 4

m = 2

The line parallel to this line will have the same slope

In the given option , Option C , y=2x+1 has the same slope , so will be parallel to the given line.

Which is the equation of Line B?
notka56 [123]
  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:

\frac{1-2}{1-(-3)}=-\frac{1}{4}

Next, plug either one of the points into the x and y coordinates to solve for b as such:

2=-\frac{1}{4}*-3+b\\2=\frac{3}{4}+b\\\frac{5}{4}=b

<u>Our final equation is y=-\frac{1}{4}x+\frac{5}{4} , or the third option.</u>
