Answer:

x = 1, y =   46\3

y-intercept = 2

slope(m) =  

7 - 2 \3 - 0 =  5 \3

thus,

y =  5 \3 x + 2

then, plug in values

Answer:

B) x = 1, y = 46/3

Step-by-step explanation:

The general equation for a straight line is

y = mx + b

Step 1. Find the <em>slope of the line </em>

The slope m is

m =(y₂ -y₁)/(x₂/x₁)

Two of your points are (0, 2) and (3, 7).

m = (7 – 2)/(3 – 0)

m  = 5/3

Step 2. Find the <em>equation of the line</em>

Use point (0, 2).

2 = ⁵/₃ × 0 + b

2 = 0 + b

b = 2

The equation of the line is

y = ⁵/₃x + 2

===============

Step 3.Find the coordinates of the <em>first missing point</em>.

(x, 11/3)

11/3 = ⁵/₃x + 2     Multiply each side by 3

  11 = 5x + 6       Subtract 6 from each side

  5 = 5x              Divide each side by 5

  x = 1

The missing value is x = 1.

===============

Step 4. Find the coordinates of the <em>second missing point </em>

(8, y)

  y = ⁵/₃ × 8 + 2   Multiply each side by 3

3y  = 40 + 6        Combine like terms

3y = 46               Divide each side by 3

y = 46/3

The missing value is y = 46/3.

Your three known points give the green line in the graph below.

The orange dot represents the first missing point at (1, 11/3).

The red dot represents the second missing point at (8, 46/3).

PLZ HELP I WILL GIVE BRIANLY!
kumpel [21]

Answer:36

Step-by-step explanation:

\frac{4}{7} =\frac{48\\}{84}

for every 7 students there are 4 girls, so for every 84 there must be 48

7*12=84

4*12=48

so, in all 84 students there are 48 girls

so amount of boys=84-48=36

there are 36 boys

A reflection maps the point (2, 3) to the point (2, -3).
Tresset [83]

Answer:

x axis

Step-by-step explanation:

We know the x value stays the same. If you were to graph the line y=3 and y=-3, you would see that it is a reflection over the x axis.
