Plot the x- and y-intercepts to graph the equation. y=13x−1 . plot it on a graph and i will get you and 15 points

Given the equation:        .....[1]

To find the intercepts:

x-intercepts states that the graph cross the x-axis.

Substitute the value of y = 0 in [1] to solve for x;

Add 1 to both sides we get;

Multiply both sides by 3 we get;

x-intercepts = (3, 0)

y-intercepts states that the graph cross the y-axis

Substitute the value x = 0 in [1] to solve for y;

Simplify:

y = -1

y-intercept = (0, -1)

Now, using these x- and y--intercepts  points to graph the given equation as shown below.

168

step-by-step explanation:

i am pretty sure that the answer is 168

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.
