Is it a function ?
{(0,1), (2,4), (0,-2), (9,10)}

Yes because for every x value there is only one y value that corresponds it that being said y values can be repeated but only x values can not

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
