Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62
Answer:
225 adult tickets
Step-by-step explanation:
S: no. of students
A: no. of adults
S = A + 54
S + A = 504
A + A + 54 = 504
2A = 450
A = 225
S = 225 + 54
S = 279
Answer:
m=60º
n=30º
Step-by-step explanation:
a triangle is 180º total
an equilateral triangle has all 60º angles
since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º
substituting the values 60+n=90
so n=30
Then since a triangle is 180º you can make an equation that says 180=90+m+n
again substituting 180=90+m+30
60=m
an easy way to check is 180=90+30+60 180=180
<h3>
Answer: Time</h3>
Explanation:
Time progresses without any control over it, so it's something that does not depend on any other factor such as distance. On the other hand, as the time value changes, the distance changes. So the distance is dependent on the time.
The horizontal axis is the x axis, and the x value is always the independent variable. The vertical y axis is the distance. The y value is always the dependent variable.

============================================================
Explanation:
Let's use the slope formula to get
m = (y2-y1)/(x2-x1)
m = (6-4)/(5-2)
m = 2/3
The slope of the line is 2/3.
We can see that the responses for choices 1 and 3 are "no" because they involve a slope of 3/2.
-------------
Recall that y-y1 = m(x-x1) represents the point slope form. The m is the slope and (x1,y1) is the point the line goes through.
If we plugged the point (x1,y1) = (2,4) , along with the slope m = 2/3, then we'll get to what choice 2 is saying
If we tried the other point (5,6), and kept m the same, then we'd get to choice 4.
That makes choices 2 and 4 "yes" responses.
