Math help PLEASE! just need a refresher.how would you find the slope of the equation 2x-3y=18?

Question

thank you so much!!it really helped

Answer 1

It's 2/3.

What you do is express the equation in "standard form," that is as:

y = m x + b.

Here, ' m ' is the SLOPE (how much y increases for unit increase in x), and ' b ' is the ' y-intercept ,' that is, the value of y on the y-axis at which the line crosses it. (x = 0 defines the "y-" or "vertical" axis on a graph.)

The 'normal form' for the equation 2x-3y=18 is:

y = (2/3) x - 6,

hence the slope is 2/3. QED.

Live long and prosper.

Answer 2

Rearrange 2x-3y=18 as (2x-18)/3=y or y=(2/3)x-6. Compare it with y=mx+c where m is the slope of the line. So what is the slope?

Answer 3

Now y-2x-3=0 shall we make it into y=2x+3 in case you opt on a short way, slope = 2 and intercept = 3. lengthy way: to discover the slope, positioned 2 values of x with the form of one million. enable us attempt to positioned x = 0 and a million. Then y = 3 and 5. So the slope is 5 - 3 = 2. (slope = upward push/run) to discover the intercept, positioned x = 0 --> y = 3. So, The slope is two and the intercept is 3.

Answer 4

put in to y=mx+b form
2x-3y=18
First add 3x to each side
2x=18 + 3y
next subtract 18 from each side
2x-18=3y
finally divide by 3
(2/3)-6=y
ta da!!!!!
y=(2/3)-6

Answer 5

1.Put into SLOPE INTERCEPT form; y=mx+b

2x-3y=18 (you want y to left of the equal sign)
-2x.... ..-2x
---------------
-3y= -2x+18 now divide -3y through whole problem
--------------
-3 -3 -3

y= 2/3x - 6

mx=slope so your slope is 2/3x

Answer 6

put it into y=mx+b form(Slope intercept form) m=slope
