Answer:
D. -3.3
Step-by-step explanation:
=> 2.8x = -9.24
=> x = -9.24/2.8
=> x = -3.3
Answer:
r = 0.1
Step-by-step explanation:
If (x, y) = (14, 1.4) and the quantities are proportional, the constant of proportionality (r) in ...
y = rx
is ...
r = y/x = 1.4/14 = 0.1
The constant of proportionality is 0.1.
Answer: y = -
x - 6
Step-by-step explanation:
The line crosses the y intercept at y = -6
The slope of the graph looks negative, as it extends from the top left quadrant to the bottom right quadrant.
A key trick is to use rise/run to figure out the slope:
Between each dot on the line, it rises 2 and runs -3 (negative because the direction is left).
So your equation would be: y = -
x - 6
