Answer:
-24
Step-by-step explanation:
-12, -15, -18, -21,
Notice that we are subtracting 3 each time
-12 -3 =-15
-15 -3 = -18
So -21 -3 = -24
(12 x 2) + (7 x 4) - 2 would be the expression
first you multiply the 12 x 2 and the 7 x 4, you add those together and then you subtract two from your total answer.
meaning your answer would be 50
Point Slope Form of a Line: y - y₁ = m(x - x₁)
Slope Formula:
y₂ - y₁ 4 - (-1) 5 The slope is 5/6.
------------- = -------------- = ------
x₂ - x₁ 8 - 2 6
(2, -1) & (8,4)
x₁ y₁ x₂ y₂
Using all of the information above...
y + 1 = 5/6(x - 2) is your equation in point slope form.
Steps for rewriting this equation in standard form:
Standard Form of a linear equation: ax + by = c
1). Put the equation from PS form into Slope Intercept Form, which is y=mx+b
y + 1 = 5/6(x - 2)
y + 1 = 5/6x - 5/3
- 1 - 1
------------------------
y = 5/6x - 8/3
2). Put the equation from Slope Intercept Form into Standard Form.
y = 5/6x - 8/3
- 5/6x - 5/6x
______________________
(-1) -5/6x + y(-1) = -8/3(-1)
5/6x - y = 8/3
The equation in standard form is 5/6x - y = 8/3.
I hope this helps you!
