I don’t even know the answer to be honest
Answer:
The variable that represent the slope is 'm' and the variable that represent the y-intercept is 'b'.
Step-by-step explanation:
The equation of a line in slope-intercept form is given as:
Here, the variable 'm' is the coefficient of independent variable 'x' and represents the slope of the line.
The constant term in the given equation is 'b' and it represents the y-intercept of the given line.
Slope is defined as the ratio of rise or fall over run. In other words, slope is the ratio of change in value of 'y' with change in value of 'x'.
Slope is positive if change in 'y' is positive with increasing 'x' and it is negative if change in 'y' is negative with increasing 'x'.
y-intercept is the point where the line crosses the y-axis. So, the 'y' value of that point is y-intercept. The coordinates of the point is given as (0, b).
So, the variable used for the slope is 'm' and 'b' is used for y-intercept.
Answer:
6 years
Step-by-step explanation:
Convert feet to inches: 3 feet = 36 inches, 7 feet = 84 inches
Set two equations equal to each other:
First equation, Type A has a slope of 12 (grows 12 inches per year) and a y-intercept of 36 (it starts 36 inches (or 3 feet) tall)
Second equation, Type B has a slope of 4 (grows 4 inches per year) and a y-intercept of 84 (starts at 84 inches (or 7 feet) tall)
12x + 36 = 4x + 84
subtract 36 from both sides
12x = 4x + 48
subtract 4x from both sides
8x = 48
divide by 8 on both sides
x = 6
It will take the tree types 6 years to be the same height

The first thing we should do is see what relationship we have:
Table is feet to yards 3-1
a. Describe the relationship between the number of feet and the number of yards
That is to say:
1Yarda = 3 feet
b. Write an expression for the number of yards in f feet
Let
y = Yard
f = feet
We have the following expression for the conversion:
y = (1/3) f
c. Find the number of yards in 63 feet
For this case we must substitute in the expression found the value of f = 63.
y = (1/3) f
y = (1/3) (63)
y = 21
answer:
1Yarda = 3 feet
y = (1/3) f
y = 21
