Answer:
y = - 2x + 7
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 ) = (- 2, 11) and (x₂, y₂ ) = (5, - 3)
m = 
= 
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 11), then
11 = 4 + c ⇒ c = 11 - 4 = 7
y = - 2x + 7 ← equation of line
Answer:
5 weeks
Step-by-step explanation:
To find the answer to this question we have to write an equation for both situation and put them equal to each other.
Let's write an equation for Joe:
12x + 100
Now, for Jessica
6x + 130
Next, put them equal to each other:
12x + 100 = 6x + 130
Solve:
12x + 100 = 6x + 130
6x + 100 = 130
6x = 30
x = 5
Therefore, it will take 5 weeks for Joe and Jessica to have the same amount of cards.
Check:
12(5) + 100 = 6(5) + 130
60 + 100 = 30 + 130
160 = 160

Answer:
I think it's y = -1/2x -2
Step-by-step explanation:
use the formula y - y1/ y2- y1= x - x1/x2-x1
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
In case of Waldo:
Number of hours they work = 8
Number of units per hour = 7 units
So, Output would be
In case of Emerson:
Number of hours they work = 6 hours
Number of units per work = 10 units
So,Output would be
Hence, Emerson’s productivity and output are greater than Waldo’s.
Therefore, Option 'c' is correct.
