what is the slope of the line that passes through the points (-7,-7) and (-7.1)
Answers
Answer:
Undefined
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the two points:
(y2 - y1) / (x2 - x1)
(1 + 7) / (-7 + 7)
8/0
= undefined
So, the slope is undefined, since you cannot divide by zero.
The slope of the lines that passes through the points (-7,-7) and (-7.1) is an infinite slope.
Slope equation:The slope formula is described as follows:
m = y₂ - y₁ / x₂ - x₁Therefore,
x₁ = -7
x₂ = -7
y₁ = -7
y₂ = 1
m = 1 - (-7) / -7 - (-7)
m = 1 + 7 / -7 + 7
m = 8 / 0
m = infinity
The slope is an infinite slope. Therefore, it is a vertical line.

3. Patrick kicks a soccer ball from the ground into the air. When the ball is a horizontal distance of 12 feet from
him, it is 14 feet above the ground. When the ball is 32 feet from him, it is 7 feet above the ground.
Use quadratic regression on a graphing calculator to write a function for the height of the ball in terms of
its horizontal distance Round to the nearest thousandth (
Answers
Answer:
The function for the height of the ball in terms of its horizontal distance is
[tex]y = -\frac{91}{1920}\cdot x^{2}+\frac{833}{480}\cdot x[/tex]
Step-by-step explanation:
From Physics, we know that ball describes a parabolic motion, in which trajectory is described by the following second-order polynomial (quadratic function):
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Horizontal distance, measured in feet.
[tex]y[/tex] - Vertical distance above the ground, measured in feet.
[tex]a[/tex] - Second order coefficient, measured in [tex]\frac{1}{ft}[/tex].
[tex]b[/tex] - First order coefficient, dimensionless.
[tex]c[/tex] - Zero order coefficient, measured in feet.
We can obtain the second-order polynomial associated with the soccer ball by knowing three distinct points and solving the resulting system of linear equations. If we know that [tex](x_{1},y_{1}) =(0\,ft, 0\,ft)[/tex], [tex](x_{2},y_{2})=(12\,ft, 14\,ft)[/tex] and [tex](x_{3},y_{3})=(32\,ft, 7\,ft)[/tex], then the system of linear equations is:
[tex]c = 0[/tex]
[tex]144\cdot a+12\cdot b +c = 14[/tex]
[tex]1024\cdot a +32\cdot b + c = 7[/tex]
The solution of this linear system is:
[tex]a = -\frac{91}{1920}[/tex], [tex]b = \frac{833}{480}[/tex], [tex]c = 0[/tex]
Therefore, the function for the height of the ball in terms of its horizontal distance is
[tex]y = -\frac{91}{1920}\cdot x^{2}+\frac{833}{480}\cdot x[/tex]

Explain how to convert an equation from slope-point from to slope-intercept fom.
Answers
Step-by-step explanation:
When you compare the two ways of writing a line, you might notice that there are some similarities. Both retain a y variable, an x variable and the slope of the line. So all you really need to get from point-slope form to slope-intercept form is a little algebraic manipulation. Consider the example given of a line in point-slope form: y + 5 = 3(x – 2).
Distribute x- Use the distributive property to simplify the right side of the equation:
Isolate the y Variable- Subtract 5 from both sides of the equation to isolate the y variable, which gives you the equation in point-slope form:
