Answer: it is table "a"
explanation:
as the equation is y= 2x + 5 you should substitute each of the x values from -2 to 4 in order to get the y value which will help you decide which table should be used by Cindy to graph the equation.
now, this is how you should substitute the values into the equation and simplify it so that you get the "y" value.
the first x value given is -2 therefore:
you put -2 in the equation instead of putting x, this will allow you to find the y value which you can compare with the choices given.
y= 2x+5 (this is the equation)
y= 2(-2)+5 (here I have replaced the x with -2)
y= -4+5 (you should multiply 2 and -2)
y= 1 (therefore the answer is 1)
you should further continue this way and get the y values which will help you decide which is the correct table to be used. Now you already know that table "a" is the answer.
