Question

The slope of a line is -2 and the line contains the points (7 ,4) and (x, 12). What is the value of x?

Answer 1

Answer:

• x = 3

Step-by-step explanation:

Use slope formula and compare with the actual slope m = -2:

• m = (12 - 4)/(x - 7)
• 8/(x - 7) = -2
• x - 7 = -4
• x = 7 - 4
• x = 3

Answer 2

Answer:

x=3 this is my answer. ......
