3) What is an equation for the line that passes through the coordinates (-1.2) and (7,6) ?

OLEGan [10]

Answer:

$y=\frac{1}{2} x+\frac{5}{2}$

Step-by-step explanation:

First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.

$\frac{6-2}{7- (-1)}=\frac{4}{8}=\frac{1}{2}$

So now we have the equation $y=\frac{1}{2} x+b$ , and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

$2=\frac{1}{2}(-1)+b$

Rearrange the equation so it equals b

$\frac{5}{2}=b$

Put it together and that's the final equation!

$y=\frac{1}{2} x+\frac{5}{2}$

The circle above has a radius of 11 cm. What is the area of the circle

Fittoniya [83]

Answer:

69. 14 $cm^{2}$ or 22π $cm^{2}$

Step-by-step explanation:

Area of a circle = 2πr

and, radius, r = 11 cm

π = 22/7

Therefore the area of a circle with radius 11cm

= 2* π * 11 or 2 * 22/7 * 11

= 22π or = 484/7

= 69. 14 $cm^{2}$
