Subtract the x and y coordinates (in the same order)
Then divide the y difference by the x difference to get the slope
OpenStudy (anonymous):
\[slope = \frac{ Y2- Y1 }{ X2 - X1 }\]
OpenStudy (anonymous):
the slope equation \[m=\frac{ y _{2}-y _{1} }{ x _{2} -x _{1}}\]

i did it and didnt get an accurate answer
jimthompson5910 (jim_thompson5910):
What do you get when you subtract the y coordinates (y2 - y1) ?
OpenStudy (anonymous):
\[\frac{ -2 - 4 }{ -1 - (-4) }= \frac{ -6 }{ 3 }\]
OpenStudy (anonymous):
so its -2?
OpenStudy (anonymous):
sorry @jim_thompson5910

OpenStudy (anonymous):
What type of line is the graph of 4x + y = -3?
vertical
horizontal
rising
falling
OpenStudy (anonymous):
this equation can be written as
y=-4x-3
right @aleisha96
OpenStudy (anonymous):
@esamalaa yes

OpenStudy (anonymous):
this equation is similar to
y=mx+c
OpenStudy (anonymous):
then the type of graph is ....?
OpenStudy (anonymous):
@esamalaa vertical?
OpenStudy (anonymous):
no :(
can you draw it ?
OpenStudy (anonymous):
@esamalaa no it might be falling

Select the correct inequality for the graph below
y < 3x - 1
y ≤ 3x - 1
y ≥ 3x - 1
y > 3x - 1
