Lets write equation of a function:
y = kx + n
Direct variation in simple is equation of a line which has n=0 or in other words which y to x ratio is k.
First option gets 7=7 but it isnt direct variation because n is not equal to 0
third option is indeed correct. once we implement coordinates (2,7) we get 7=7
Answer is
y = 7/2x
Check the picture below.
you can pretty much count those lengths off the grid.
recall that A = 1/2 bh.
The decimal is moved to the front to three spaces
0.003
Find the slope first using m=y2-y1/x2-x1
-4-4/0-4 =2
The y intercept is when x=0.
One of the given points is (0,-4)
The y intercept is y=-4
Answer:
3/5
Step-by-step explanation:
4+6=10
6/10=3/5
