The way I do it is I find the slope and use the formula y-y1=m(x-x1) plug in m for the slope and y1 for 21 and x1 for 5 then solve to get the y intercept

Hey!
So to get the b value you would have to plug in the points and solve for b.
21 = 5(5) + b
21 = 25 + b
21 - 25 = b
b = -4

to check you could use the other point
-29 = 5(-5) + b
-29 = -25 + b
-29 + 25 = b
b = -4

Both of them have b equal -4
so y = 5x - 4

Hope this helps!

A cone has a circular base with a diameter of 18 inches. The height of the cone is 40 inches. What is the approximate lateral ar
aliya0001 [1]

The approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches

<h3>What is the lateral area of cone?</h3>

Lateral area of the cone is the area bounded by the surface of the cone, and this Lateral area of the cone can be found out using the following formula.

A=\pi r\sqrt{h^2+r^2}

here. (<em>h</em>) is the height of the cone and (<em>r</em>) is the radius of the cone.

A cone has a circular base with a diameter of 18 inches. The height of the cone is 40 inches.

Put these values in the above formula as,

A=(3.14) (9)\sqrt{40^2+9^2}\\A\approx1159\rm \; in^2

Hence, the approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches

PLEASE HELP<br> Complete the function for this graph:
Phoenix [80]

Answer:

The equation is:

f(x) = Ix + 3I - 2

Step-by-step explanation:

For a function like:

f(x) = Ix - kI + c

k is the x-value where the vertex is, and c is the y-value where the vertex is.

In the graph we can see that the vertex is in the point (-3, -2)

then:

x-value = -3 = k

y-value = -2 = c

Replacing those in the equation for the function:

f(x) = Ix - (-3)I - 2

f(x) = Ix + 3I - 2
