Y varies directly as x, if y=12 when x=5, find y when x=3

Which point is a solution to the inequality shown in this graph (-3,-3)(3,-1)

When i add money am i supposed to make it like this 7+12 or 7.00+12.00 because i got 19 dollars for my answer

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36
