Answer:
y = 1/4x + 5
Step-by-step explanation:
The given line has a "rise" of -8 for a "run" of 2, so a slope of ...
m = rise/run = -8/2 = -4
The perpendicular line will have a slope that is the opposite of the reciprocal of this slope. Its slope will be ...
-1/m = -1/(-4) = 1/4
The equation you're looking for will have an x-coefficient of 1/4. The suitable choice is ...
y = 1/4x + 5 . . . . the third choice
Answer:
10 Minutes
Step-by-step explanation:
At roughly 10 minutes, the y-axis meets a point at the x-ais that can be shown as (40,10)
Answer:
20.25
Step-by-step explanation:
To find the area of a triangle you do base x height/2
9x4.5/2
40.5/2= 20.25
Linear, because the points (1,8) (2,6) (3,4) etc are decreasing at a constant rate of -2.
