Answer:

y = -1/2x + 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b

Use two of the ordered pairs and find the slope:

m = (1-2)/(0-(-2)) = -1/2

y-intercept is 1 as point (0, 1) is given in the table:

b = 1

The line is:

y = -1/2x + 1

Find the center and radius of this circle. x2 + y2 − 40x − 24y + 15 = 0

Julli [10]

ANSWER

Center: (20,12)

Radius:23

EXPLANATION

The given circle has equation:

${x}^{2} + {y}^{2} - 40x - 24y + 15 = 0$

We complete the square as follows:

${x}^{2} - 40x + {y}^{2} - 24y = - 15$

${x}^{2} - 40x + {( - 20)}^{2} + {y}^{2} - 24y + {( - 12)}^{2} = - 15+ {( - 20)}^{2}+ {( - 12)}^{2}$

${(x - 20)}^{2} + {(y - 12)}^{2} = - 15+ 400+ 144$

${(x - 20)}^{2} + {(y - 12)}^{2} = 529$

${(x - 20)}^{2} + {(y - 12)}^{2} = {23}^{2}$

Comparing this equation to:

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

We have

$(h,k)=(20,12)$

representing the center and

$r = 23$

being the radius.
