The major axis is 4 units long andyhe vertices are 4 units to the left/right.
Answer:
A: -6.5
Step-by-step explanation:
Take two points that we already know are on the line and find the slope
I used:
(4, -10) and (7, -30)
X1 (first x coordinate): 4
Y1 (first y coordinate): -10
X2 (second x coordinate): 7
Y2 (second y coordinate): 30
These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.
Use (Y2-Y1)/(X2-X1)
(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.
The closest answer to that is A.
480 or 500 depending on if you want to round to the nearest 10 or the nearest 100
I think you left out something, is it -4x+1
