Question

11. A line through points (-5, 2) and (2, y) has a slope of 3. Find y. Help

Answer 1

Answer:

23

Step-by-step explanation:

• Create an equation to find y:  3 = $\frac{y-2}{2-(-5)}$

• Calculate by adding:  3 = $\frac{y-2}{7}$

• Multiply both sides of the equation by 7 : 21 = y - 2

• Move the variable to the left-hand side and change its sign : -y + 21 = -2

• Calculate and change signs : y = 23

                                                             y = 23
