Answer:
Blue - y=-2
Red-
Parallel to Red-
Perpendicular to Red-
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
- m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.
- b is the y-intercept for value on the y-axis for which the line crosses it.
The Blue line intercepts the y-axis at -2 so b=-2. It has no vertical change since it is a horizontal line. This means the slope, m, is 0. m=0. It's equation is y=0x-2
y=0-2 since anything times 0 is 0.
y=-2.
The red line intercepts the y-axis at 2 so b=2. It intercepts the x-axis at (-3,0). Between these two intercepts we can find the slope:
Slope:
We substitute and
The red line has equation .
Parallel lines have the same slope with a different y-intercept. So we write a line where m=2/3 and b is something else.
Perpendicular lines have a negative reciprocal slope to the original. So we write the line where m/-3/2.
Answer:
The area that he has to run is a [3/4] circle with a radius of 15ft.....so
(3/4) pi * (15)^2 = 520 sq. ft [rounded]
Answer:
I think the answer is -8+-4=-12
The equation of the scatter plot is (a) y = 100x + 2
<h3>How to determine the equation of the scatterplot?</h3>
The line of best fit of the scatter plot passes through the points
(x,y) = (0,2) and (1,102)
Start by calculating the slope using:
So, we have:
m = 100
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = 100(x -0) + 2
Evaluate
y = 100x + 2
Hence, the equation of the scatter plot is (a) y = 100x + 2
