bear in mind that, direct proportional equations have a y-intercept.
for y = kx, is pretty much y = kx + 0, where 0 = y-intercept.
and the "k" constant of proportionality, is pretty much just its slope.
Answer:
14.6
Step-by-step explanation:
The area of a rectangle is area=length*width
so we can substitute the numbers here, 262.8=18w
divide 262.8 by 18 to isolate the variable.
You get 14.6.
The width is 14.6.
Yes because in Mrs. Benson‘s class there are 20 students and in Mrs Tracy’s class there are only 18
pls vote me brainle est i dont think you put picture
Answer:
3.
Step-by-step explanation:
If Andre's representation is correct, that the slope is 3. The question is confusing me a bit, because it isn't very clear, but Andre's Representation is in Point Slope Form, (y=mx+b) where m represents the slope. So again, if Andre's representation is for the graph and is correct, the slope is 3.
