The linear equation in its generic form is:
y-yo = m (x-xo)
In this case we have that the slope is:
m = 300
The ordered pair is:
(xo, yo) = (2, 1400)
Substituting we have:
y-1400 = -300 (x-2)
Rewriting:
y = -300x + 600 + 1400
y = -300x + 2000
Answer:
a linear function that models this scenario is:
y = -300x + 2000
The slope of the line is:
-300
The y-intercept of the line is:
2000
Answer:
12
Step-by-step explanation:
if R = 9
9-8=1
9 + 3 = 12
12*1=12
For every 100 students, 72 prefer pizza.
The are 15 groups of 100 students each amongst 1500 students;
The total number of students preferring pizza then is;
15*72= 1080
Given:
The graph shows the relationship between the number of pounds of apples purchased and the total cost of the apples.
To find:
The cost of 1 pound of apples.
Solution:
We need to find the slope of the line to get the cost of 1 pound of apples.
From the given graph it is clear that the line passes through two points (0,0) and (2,3). So, the slope of the line is
Therefore, the cost of 1 pound of apples is $1.5.
X=1
Step-by-step explanation:
-2-(-3) remove the parenthesis
-2+3 calculate the sum
x=1
