Determine a value of x that makes the following statement true. State the restrictions on the variables x and y. Show work for full marks.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

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?
