one of these are the equations :
OpenStudy (campbell_st):
you need to find the slope between the points (-4, -7) and (0, 6)
the y intercept is -6
so the equation will be
y = mx - 6
just find the slope m
OpenStudy (anonymous):
so do we plugin any x coordinate to the x in the equation?
OpenStudy (campbell_st):
do you know how to find the slope of a line... ?

you have two set of points (0, -6) and (-4,-7)
just find the slope
if you have two points (x1,y1) ,( x2,y2) slope is
\[\Large m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]
OpenStudy (anonymous):
would it be -1/-4?
OpenStudy (anonymous):
so it would be y=-1/4x-6
OpenStudy (anonymous):
or no.
OpenStudy (campbell_st):
what happens with the -1/-4 it can be simplified... to

OpenStudy (campbell_st):
it uses the rule of multiplying 2 negatives
OpenStudy (anonymous):
it turns into a positive?
OpenStudy (campbell_st):
correct... and looking that the graph of the line... it has a positive slope... so you need 1/4 as the slope.
