Write two equations in standard form that are equivalent to 5x+y=-10

i believe the answer is y=0.25x+-3

so part 1: the y values stay the same, but the x values are opposite signs.

part 2 & 3: the line will be of equal lengths and will be straight.

part 4: you'd see the same characteristic because the x coordinate becomes a negative making them at equal distances from the y axis?
