Write a linear equation that contains the ordered pair shown in the table below:

Amiraneli [1.4K]

Answer:

$y=2x-4$

Step-by-step explanation:

Let the equation of line is $y=mx+b$ , where $m$ is the slope of the line.

It passes through $(-5,-14),(-2,-8)\ and\ (1,-2)$ .

(<em>Slope of the line</em> joining $(x_1,y_1)\ and\ (x_2,y_2)=\frac{y_2-y_1}{x_2-x_1}$ )

Hence slope of the given line

$m=\frac{-8(-14)}{-2-(-5)}=\frac{-8+14}{-2+5}=\frac{6}{3}=2$

Equation of line is: $y=2x+b$

The line passes through $(1,-2)$

$-2=2\times 1+b\\b=-2-2\\b=-4$

Check if $(-5,-14)$ is on the line $y=2x-4$

$L.H.S.=-14\\R.H.S.=2\times (-5)-4=-10-4=-14\\L.H.S.=R.H.S.$

Hence line passes through $(5,-14)$ .

Check if $(-2,-8)$ is on the line $y=2x-4$

$L.H.S.=-8\\R.H.S.=2\times (-2)-4=-4-4=-8\\L.H.S.=R.H.S.$

Hence line passes through $(-2,-8)$ .

The base of a triangular prism has an area of 18 square inches . If the height of the prism is 4.5 inches then what is the volum

Nady [450]

Answer:

The volume for the triangular prism is 40.5 cubic inches.

Step-by-step explanation:

Given:

The base of a triangular prism has an area of 18 square inches .

And the height is 4.5 inches.

Now, to get the triangular prism volume.

The base area = 18 square inches.

Height = 4.5 inches.

Now, to get the volume of prism we put formula:

$Volume=\frac{1}{2} \times base\ area\times height\\\\Volume=\frac{1}{2} \times 18\times 4.5\\\\Volume=40.5\ cubic\ inches.$

Therefore, the volume for the triangular prism is 40.5 cubic inches.
