if (1,4) and (10,-68) are two anchor points on the trend line, then find the equation of the line y=[?]x + [ ]
Answers
Answer:
y = - 8x + 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (10, - 68)
m = =
= - 8, thus
y = - 8x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 4), then
4 = - 8 + c ⇒ c = 4 + 8 = 12
y = - 8x + 12 ← equation of line

Absolute value just finds a numbers distance from zero, or makes the number positive. is already positive, so just leave it.
The solution to the absolute value function -|-5 · (-7)| is equal to -35.
How to algebraically determine the solution to the absolute value function?
In Mathematics, an absolute value function is a type of function that is composed of an algebraic expression, which is placed within absolute value symbols and it typically measures the distance of a point on the x-axis to the x-origin (0) of a cartesian coordinate such as:
|a - 4b|
Based on the information provided above, we can logically deduce the following absolute value function;
-|-5 · (-7)|
-|35|
-35

4.5.1) 2x-5y=8
x=3y-1
A. Substitute the equation that is already solved for one variable into the other equation.
B. Solve for the single variable in the one-variable equation.
C. Substitute the result from the previous step into x=3y−1 and solve for the unknown variable.
D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.

Answer: X=29
Step-by-step explanation:
First you substitute the x's: 2(3y-1)-5y=8
Then you open parenthesis:6y-2-5y=8
Combine like terms: y-2=8
Bring the 2 to the other side: y=10
Now you substitute the y with the answer: x=30-1
Easy equation: x=29
