What is the equation of the line that has a slope of 2 and passes through the point (2,9)?
jenyasd209 [6]

Answer:

D

Step-by-step explanation:

use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)

we're given that m=2 and the point is (2,9)

Substitute into the equation

y-9=2(x-2)

That means that the answer is D

Hope this helps!

A wooden board has a volume of 0.225 cubic m and a mass of 146.25 kilograms.
Triss [41]

Answer:

650 kg/m³

Step-by-step explanation:

The density is the ratio of mass to volume. The volume is the product of the dimensions of the prism.

 density = (146.25 kg)/((1.5 m)(0.75 m)(0.2 m)) = 146.25/0.225 kg/m³

 = 650 kg/m³

Hope this answer helps you :)

Have a great day

Identify the slope (m) and y-intercept (b) of the graph of each equation y=1/2x-7
Tamiku [17]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following equation:

y = \frac {1} {2} x-7

So:

m = \frac {1} {2}, the slope is positive

b = -7

For the graph, we place the point on the coordinate axis:

(x, y) :( 0, -7)\\(x, y) :( 1, - \frac {13} {2})

We draw the line!

The graphic is attached.

ANswer:

m = \frac {1} {2}, the slope is positive

b = -7

If the graph of f(x) = x is shifted up 9 units, what would be the equation of the new graph?
MariettaO [177]

Answer:

f(x) = x + 9

Step-by-step explanation:

y = f(x) + C C > 0 moves it up

To shift it up 9 units

f(x) = x + 9
