Graph the equation. y = 4x – 3

OpenStudy (anonymous):

Mark the point (0, -3) and draw a line with slope 4. Boom!

OpenStudy (anonymous):

is it this ??

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

Not quite, slope is rise over run. 4 is the same as 4 over 1, so it has to rise 4 and go over 1. Yours is going down 4 and over 1! Make it so it slopes the other way.

OpenStudy (anonymous):

this one

OpenStudy (anonymous):

crossing point is off too

OpenStudy (anonymous):

okay this one

OpenStudy (anonymous):

It crosses at y=3... then slope as @cholo71796 described

OpenStudy (anonymous):

erp... oops... -3 crossing

OpenStudy (anonymous):

so no ??

OpenStudy (anonymous):

Not quite, yours looks like it is crossing at (0, -2) instead of (0, -3). Good on the slope now though

OpenStudy (anonymous):

this one for sure ??

OpenStudy (anonymous):

The thrid graph looks like it crosses at -3 on the y. The fourth one has a bad slope again.

OpenStudy (anonymous):

Nah you had the slope good-- positive slopes go up and to the right-- but you got it crossing at (0, -3) now which is good

OpenStudy (anonymous):

Going left to right it should be like you are going up hill if the slope is positive.

OpenStudy (anonymous):

okay help me with this then !!!!

OpenStudy (anonymous):

Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y when x = –2?

OpenStudy (anonymous):

You should post a new question, so your helper gets a new point.

OpenStudy (anonymous):

Cholo did good for you... pick best response next to his name and start again.

OpenStudy (anonymous):

ok
