    If you have a slanted line like y >= x+1, which part should be shaded? y is greater than or equal to the line x+1 This indicated that all the y values that are greater than the line x+1 should be shaded.

    What about the second equation? What part of the graph should be shaded?

    wait so for the first question it would be part b?

    B or A, we don't know yet. We only know for now that we should eliminate part D and C because the first equation is not shaded in neither parts D or C.

    yeah. i pluged in the 2 equations and just by looking at y ≥ x + 1 when i graphed it it was clear it was a

    first one would be B. right?

    2nd one is also B. Because 5^x is bigger than 5X in any given x value

    So the final one is 7/10 which is the last answer. Yes. I plotted them . I got answer B for the first one. let me try it again

    on that question, You will see two graphs like my attachment. but our question is not about equations. It is about inequalities. y>= x + 1 means y takes values above blue line(my image) you can make the second one something like y <= -1 -x which is the red line So y takes values below red one
