Answer 2

To find the values of a(1;5) and b(-1;-1) in the equation Y = 2x + 3, you can substitute the given x-values into the equation and solve for the corresponding y-values.

For point a(1;5): Substituting x = 1 into the equation: Y = 2(1) + 3 Y = 2 + 3 Y = 5

Therefore, a(1;5) corresponds to the point (1, 5) in the equation.

For point b(-1;-1): Substituting x = -1 into the equation: Y = 2(-1) + 3 Y = -2 + 3 Y = 1

Therefore, b(-1;-1) corresponds to the point (-1, 1) in the equation.

So, a(1;5) corresponds to (1, 5) and b(-1;-1) corresponds to (-1, 1) in the equation Y = 2x + 3.
