Answer:

Both D and E are true statements.

Step-by-step explanation:

When you have the base form of slope-intercept form:

y = mx + b

The m (which is the coefficient of x) is the slope of the line. In this case that would be 4.

The b is the intercept. In this case it would be -6

Write the standard form of the equation of the circle described below.

Luden [163]

Equation of circle is $x^2+(y+2)^2=26$

Step-by-step explanation:

The standard form of the equation of circle is:

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

where (h,k) is the center of the circle and r is the radius of circle.

We need to find the radius of circle r by using distance formula:

$r=d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}\\r=d=\sqrt{(-5-0)^2+(-1-(-2))^2}\\r=d=\sqrt{(-5)^2+(1)^2}\\r=d=\sqrt{25+1}\\r=d=\sqrt{26}$

r=√26

and r^2= 26

Putting values of r^2=26 and value of center (h,k)=(0,-2)

the equation of Circle is:

$(x-h)^2+(y-k)^2=r^2\\(x-0)^2+(y-(-2)^2=26\\x^2+(y+2)^2=26$
