Answer:
y = -
x - 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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, - 3) and (x₂, y₂ ) = (6, - 7)
m =
=
= - 
Note the line crosses the y- axis at (0, - 5) ⇒ c = - 5
y = -
x - 5 ← equation of line
#8: $900. (I found this answer by multiplying 3000 and 0.3 by the way)
#9: 160 miles. I found this answer by multiplying 80 by two, since two halves/50% make a whole or 100%.
Is this 13 and 34 ? or 1,3,3,4?
the correct answer to question 1 is 1/8
