Question

MEdall!!!! @thefurball @iambatman @welshfella im really stuck on this one im guesssing its c pls explain?

Answer 1

The slope is -4/3, so that means the graph slopes downhill as you move from left to right.

Also you can use something like desmos

if you don't have a graphing calculator

Answer 2

Well note that equation of the line is as such: y = mx+b, where m represents your slope and b is your y - intercept (where the line crosses the y - axis).
You remember learning about rise/run the ratio for slope? That's essentially what that equation gives us that I showed you earlier. \[ m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }\] rise is change of y and run is change in x so if we have a graph as such

Answer 3

So your slope is -4/3, looking at y = mx+b, and comparing it with your equation y = -4/3x right?

Answer 4

so it has to be b and d right?

Answer 5

or*

Answer 6

Your answer would be B. I use a rise over run formula. Your numerator is your rise, which is the x-axis and your denominator is your run, which is the y-axis

Answer 7

Yes, B is correct. Go 4 units down, 3 units right :)

Answer 8

Notice in your equation y=-4/3x+0 meaning thy y - intercept is 0, as it crosses the y - axis there, you can go 4 units down and 3 right from there or vice versa when going up!

Answer 9

The denominator of -4/3 is 3. So if you plug in values of x that are multiples of 3, you'll get results that are whole numbers.

Example: x = 3 ---> y = (-4/3)x = (-4/3)*3 = -4
So if x = 3, then y = -4 giving the ordered point (3, -4)

Answer 10

So you could use the slope idea to move around the line, or you can generate points that lie on the line by plugging in x values to get corresponding y values.
