Look at the graph, write it's equation. (picture 1 is graph) (picture 2 is possible answers)
one of these are the equations :
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
so do we plugin any x coordinate to the x in the equation?
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 \[\Large m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]
would it be -1/-4?
so it would be y=-1/4x-6
or no.
what happens with the -1/-4 it can be simplified... to
it uses the rule of multiplying 2 negatives
it turns into a positive?
correct... and looking that the graph of the line... it has a positive slope... so you need 1/4 as the slope.
hope you have an answer with y = 1/4 x - 6
