Match the graph with its equation. 6x + 6y = 12 6x + 2y = 12 –6x – 2y = 12 –6x + 2y = 12

C.

Step-by-step explanation:

We are given that  a graph.

We have to find the equation of given graph.

The line passes through the point (-2,0) and (0,-6).

Slope:m

By using the formula

Slope-intercept form:

Where m=Slope of line

C=y-intercept

y-intercept: It is that value of y for which x=0

We have y- intercept=-6

Using the formula

Equation of line

Multiply by -2 on both sides then we get

b.-4 units

all you   do is count how many times you move

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
