Write the equation 2x - 3y = 6 in slope-intercept form. User: Write the equation for 5x + 2y = 3 in slope-intercept form.

evablogger [386]

Slope intercept form is: y=mx+b

So you take the first equation: 2x-3y=6 and you subtract the 2x from both sides and get: -3y= 2x+6

Then you take that equation: -3y= 2x+6 and divide -3 from both sides and get: y= -2/3x -2

So the equation 2x-3y=6 in slope intercept from is
y = -2/3x -2

Can you do the next one your self based on the one i did...?

Here ya go ;)

5x + 2y = 3 okay same steps as above you want to get the x on the other side so you subtract the 5x from both sides and get:

2y = 5x + 3

Then you want to get the y by its self so you divide the 2 from both sides so you get:

y = 5/2x +2/3

Now idk if your allowed to leave it like that (based on your teacher's preferance really) but if not you can simplfy your fractions and get:

y = 2.5x + 0.66

( i would leave the 2/3 and just leave it as y = 2.5x + 2/3 ) but you do you and i hope that helped you :)

Which of these represents six miles less than twice the original distance?

Alexeev081 [22]

If the original distance is x, then twice the original distance is 2x.
6 less than something means minus six, or -6.
So the answer would be A) 2x-6

Which of the following describes how to translate the graph y=|x| to obtain the graph of y=|x-6|

Lera25 [3.4K]

You transformed the function as follows:

$f(x)\mapsto f(x-6)$

All trasformations of the fashion $f(x)\mapsto f(x+k)$ translate the function horizontally, k units right if k is positive, k units left if k is negative.
