    For the first one, substitute the value of x that they give you into the equation

    like for C, they gave you 3 so solve \(\tt{y=1.3*3}\)

    For the second question, you substitute the answer choices into the equation.

    so like A (-1,-12) \(\tt{-12=12*(-1)}\) is that true?

    ok so it's not B because -1 = 12*(-12) <-- not true C is correct because 12 = 12*1 D is incorrect because 1 = 12*12 <-- not true so the answers to the second question are A and C

    third question: slope is -1.5 that means the line is going down so it can't be B or C

    the correct graph would be A

    ok fourth question: line is going up so positive slope so between A and B the correct answer would be B

    ok last question use the points (-1,5) and (1,-5) slope formula \(\dfrac{-5-5}{1-(-1)}=\dfrac{-10}{1}=-10\) so slope is -10
