Graph y = 3/4x-4?

Question

Graph y = 3/4x-4

Answer 1

Would be better to use brackets. It's not clear, whether

y = 3/4x-4

means

y = (3/4)*x - 4

or it means

y = 3/(4*x) – 4

or it means

y = 3/(4*x – 4)

So the question is very confusing.

In the first case all the above answers are correct.

In the second and third case the graphs are hyperbolas, and you may see them here:

Answer 2

y = 3/4 x -4

This equation is explained as the formula y = mx + b

m = slope and b in this case is the y intercept

It only take 2 points to establish a line.

Draw a graph with x and y axis

when x = 0 y = -4 so one point is (0,-4)
when y = 0 x = (16/3 ) so a second point is ( 16/3 , 0 )

the slope or rise ove run is 3/4

Answer 3

You have an equation in slope intercept form.

It's a straight line which has it's y intercept at (0,-4) and the slope is 3/4 (it rises 3 and runs 4, so another point is (4,-1) then (8,2) and (-4,-7) and so on.

Can't really do a graph on answers...

Answer 4

when x is 0, y is -4. plot (0,-4). from there go up 3 and right 4 [that's what the slope tells you] and plot (4,-1). draw a line through them.

Answer 5

y=mx+b m=slope b= y intercept so on the y axis go up four and put a point at (0,4) from there use your slope to find another point. so rise 3 and run 4. so put another point at (4,7) then just connect the dots
