Answer:
y = 3x + 3
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 ) = (- 1, 0) and (x₂, y₂ ) = (0, 3) ← x and y- intercepts
m = = = 3
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = 3x + 3 ← equation of line
Answer: an average of 13.5 mph is very respectable
3r + (9 + 2r + 1)
this can be simplified :
3r + (9 + 2r + 1) = 3r + 2r + 9 + 1 = 5r + 10
its 8 because if you do 4 times 2 equal 8
I think its B but ima have to check again and get back to you
