a line has a slope of 3/2 and a y intersept of -2 put it in slope intersept form is this right y=3/2-2

OpenStudy (anonymous):

yes except you are missing an \(x\)

OpenStudy (anonymous):

oh

OpenStudy (anonymous):

\[y=\frac{3}{2}x-2\] is what you are looking for

OpenStudy (anonymous):

k

OpenStudy (anonymous):

looks like \[y=mx+b\] with \(m=\frac{3}{2},b=-2\)

OpenStudy (anonymous):

can you help me graph the line

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

although my artistic skills are not too great the line will cross the \(y\) axis at the point \((0,-2)\) because you are given the \(y\) intercept at \(-2\)

OpenStudy (anonymous):

the slope of \(\frac{3}{2}\) means for every two units you go the right, the line will go up 3 units i.e. over 2, up 3

OpenStudy (anonymous):

so for example \((0,-2)\) is on the graph, if you go right two up three you get another point at \((2,1)\)

OpenStudy (anonymous):

another right two another up 3 takes you to \((4,4)\)

OpenStudy (anonymous):

we can plot the points and connect the dots i can try here, it will look bad

OpenStudy (anonymous):

mine would to

OpenStudy (anonymous):

oh, what @skullpatrol wrote!

OpenStudy (skullpatrol):

Try and fill this one in with the information @satellite73 has given

OpenStudy (anonymous):

k

OpenStudy (anonymous):

|dw:1399524119072:dw| is this the right graphing

OpenStudy (anonymous):

yes better if you have graph paper, but that is the right idea

OpenStudy (anonymous):

ok thanks guys

OpenStudy (skullpatrol):

Try drawing a table of values :-)
