EASY MATH! Do with explanation

Step-by-step explanation:

you plug  0 into the (x,y) into the equation. if your finding x you plug in 0 for y and versa.  

so y = 9x -3 im going to find x

0 = 9x -3 subtract -3 from both sides

-3 = 9x  divide by 9

x = -3    

Step-by-step explanation: a little hard to help you but you need to graph it

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
