Answer:
y = 2x + 5
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 =
with (x₁, y₁ ) = B(- 3, - 1 ) and (x₂, y₂ ) = A (1, 7)
m = = = 2 , then
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 7 ) , then
7 = 2 + c ⇒ c = 7 - 2 = 5
y = 2x + 5 ← equation of line
In the first position we have 10 possible numbers, and the same for the 2nd and 3rd positions becuase the numbers are replaced, so our answer is because of the multiplication rule.
Answer:
x = 1
Step-by-step explanation:
If you plug in 1 in both equations you will get 3 as your answer as it is the intersection of those two functions.
Answer:
C
Step-by-step explanation:
translate 2 units to the left only means they are shifted to the left by 2 units nothing else changed
