Find three solutions for y=-2x-1

Answer:

(1, -3)

(2, -5)

(3, -7)

Step-by-step explanation:

Randomly choose three values for "x". Substitute each of them separately into the formula to find the "y". Then write the solution as an ordered pair (x, y).

I will choose x=1, x=2 and x=3.

When x=1:

y = -2x - 1

y = -2(1) - 1

y = -2 - 1

y = -3

(1, -3)

When x=2:

y = -2x - 1

y = -2(2) - 1

y = -4 - 1

y = -5

(2 , -5)

When x=3:

y = -2x - 1

y = -2(3) - 1

y = -6 - 1

y = -7

(3, -7)

Three solutions for y = -2x - 1 are (0, -1), (2, -5), and (-3, 5), where x and y are related by this linear equation.

The equation y = -2x - 1 represents a linear relationship between x and y. To find three solutions for this equation, you can choose different values for x and calculate the corresponding values of y. Here are three solutions:

Solution 1:

Let x = 0:

y = -2(0) - 1

y = 0 - 1

y = -1

So, one solution is (0, -1).

Solution 2:

Let x = 2:

y = -2(2) - 1

y = -4 - 1

y = -5

So, another solution is (2, -5).

Solution 3:

Let x = -3:

y = -2(-3) - 1

y = 6 - 1

y = 5

So, a third solution is (-3, 5).

You can choose any values for x and calculate the corresponding y-values to find more solutions to this linear equation.
