Marcus plotted the points (0, 0), (6, 2), (18, 6) and (21, 7) on a graph. He wrote an equation for the relationship. Find anothe
baherus [9]
From the point (0, 0), we know that the y-intercept is 0.
If we use the slope formula on the first two points:
\frac{2 - 0}{6 - 0}  =  \frac{2}{6}  =  \frac{1}{3}
we get 1/3 as the slope.
Therefore, our equation in slope-intercept form is:
y =  \frac{1}{3} x
To find a point, we can plug in any x and solve for y, let's use x=1
y =  \frac{1}{3} \times 12 =  \frac{12}{3}  = 4
Therefore, our point is (12, 4)

Solve the equation <br> (If possible please show work)
Kryger [21]

Answer:

x = 0

Step-by-step explanation:

First, distribute the -4 to the parentheses:

-4 + 3x = 2x - 4(1 - 3x)

-4 + 3x = 2x - 4 + 12x

Then, add like terms:

-4 + 3x = 14x - 4

Solve for x:

3x = 14x

0 = 11x

0 = x

–1/2(2n + 4) + 6 = –9 + 4(2n + 1)
-Dominant- [34]
Simplify by combining like terms to
-n+4=8n-5
subtract 8n from both sides
-n+4-8n=8n-5-8n
-9n+4=-5
subtract 4 from both sides
-9n+4-4=-5-4
-9n=-9
Divide both sides by -9
-9n/-9=-9/-9
n=1
hope this helps!
