Which system of inequalities corresponds to the graph of the shaded area below?
the graph and the answer choices are attached.
first, we need to find the equation of the lines. the solid line passes through (-1,1) and (3,4) so its equation is y-1=(3/4)*(x+1) y = (3x/4) +1.75 can you find the dashed line equation ?
it passes through (0,2) and (1,6) right?
you mean (2,0) and (1,6)
yes, sorry i don't know why i wrote it out that way.
so our equation would be
y=-6x+12
?
correct!
now, as you can see, the shaded area is for y SMALLER than the bold line and y LARGER than the dashed line
yes i see that
so what is the answer then ?
am i just figuring the equations out then?
i'm not sure how to solve that, i'm not getting anything close to any of the choices.
do you understand ?
oh sorry !!
OH yes i see that now, i understand.
as i said we need larger than the dash so : y>-6x+12 and lower than the bold : y <= (3x/4) +1.75 (there is equal herre because it is bold) so it is C
