In the first place, we find that the equation given in this article it is a linear equation. Therefore, it should be a straight line. With this, we are to the left with the third and fourth option. Then, we substitute the data points to the equation and see if the points meet the given.Option 3: (1,3) : (-5)(1) + (2)(3) = 1 TRUE (3,8) : (-5)(3) + 2(8) = 1 TRUE (-3,-7) : (-5)(-3) + (2)(-7) = 1 the TRUE Option 4: (4,-3) : (-5)(4) + (2)(-3) ≠ 1 FALSE (-1,2) : (-5)(-1) + (2)(2) ≠ 1 FALSE (-4,5) : (-5)(-4) + (2)(5) ≠ 1 FALSE therefore, the answer is the third option.
