Answer:
-1/2
Step-by-step explanation:
Pick two points on the line
(-2,3) and (2,1)
Using the slope formula
m = (y2-y1)/(x2-x1)
= (1-3)/(2 - -2)
= (1-3)/(2+2)
= -2/4
= -1/2
Answer:
y = 2x - 4; Alex is 18.
Step-by-step explanation:
Since Alex is 4 years younger than 2 times his sister's age, and his sister is y and Alex is x, the function of y to x must be y = 2x - 4.
According to the rule, if Alex's sister is 11, Alex is 2 times that minus four. If you calculate that, you get
11 * 2 = 22
22 - 4 = 18
So Alex is 18 if his sister is 11.
