y=3x+1

Use the slope-intercept form to find the slope and y-intercept

The slope-intercept form is y=mx+b

, where m is the slope and b

is the y-intercept.

y=mx+b

Find the values of m

and b using the form y=mx+b

.

m=3

b=1

The slope of the line is the value of m

, and the y-intercept is the value of b

.

Slope: 3

Y-Intercept: 1

Any line can be graphed using two points. Select two x

values, and plug them into the equation to find the corresponding y

values.


Choose 0

to substitute in for x

to find the ordered pair.


Replace the variable x

with 0

in the expression.

f(0)=3(0)+1

Simplify the result.

Choose 1

to substitute in for x

to find the ordered pair.

Tap for fewer steps...

Replace the variable x

with 1

in the expression.

f(1)=3(1)+1

Simplify the result.


Multiply 3

by 1

.

f(1)=3+1

Add 3

and 1

.

f(1)=4

The final answer is 4

.

4

The second point is (1,4)

.

(1,4)

Create a table of the x

and y

values.

xy0114

Graph the line using the slope and the y-intercept, or the points.

Slope: 3

Y-Intercept: 1

Select each unit fraction. A. 6 6 B. 1 8 C. 2 4 D. 1 3 E. 3 4
Drupady [299]
No unit fractions are shown. (Sometimes editing is required when you copy and paste your question text.)

Selections B and D have 1 as their first digit. We suspect those are supposed to be the unit fractions 1/8 and 1/3, respectively.

A water storage tank is in the shape of a cone with the pointed end down. If the radius is 21 feet and the depth of the tank is
andre [41]

The volume of the water storage tank is the amount of space in it

The volume of the water storage tank is 6468 cubic feet

<h3>How to determine the volume?</h3>

The given parameters are:

Radius (r) = 21 feet

Height (h) = 14 feet

The shape of the water storage tank is a cone.

And the volume of a cone is:

V = 1/3πr^2h

So, we have:

V = 1/3 * 22/7 * 21^2 * 14

This gives

V = 6468

Hence, the volume of the water storage tank is 6468 cubic feet
