Answer:
<em>Sam is 24 years old and his mother is 48 years old.</em>
Step-by-step explanation:
<u>Equations</u>
Let's call
x = Sam's current age
Since Sam's mother is twice as old as Sam:
2x = Sam's mother current age
x + 12 = Sam's age in 12 years
2x - 12 = Sam's mother age 12 years ago
These two last expressions are equal:
x + 12 = 2x - 12
Subtracting x and adding 12:
x = 24
2x = 48
Sam is 24 years old and his mother is 48 years old.
Answer:
slope = -2
y-intercept = (0,2)
y = -2x + 2
Step-by-step explanation:
In order to find the slope, we must use the formula y2-y1/x2 - x1. But in order to do so, we will have to find two perfect points.
perfect point #1: (-2,6)
perfect point #2: (2, -2)
Now, we simply input the corresponding points into our formula.
-2 - 6 = -8
2 - (-2) = 4
-8/4 = -2
So, the slope of the graph is -2
In order to find the y-intercept we must look at where the line intersects in the y axis. Looking back at our graph, we can determine that the line intersects at (0,2)
The slope-intercept form is y = mx + b, m represents the slope and b represents the y intercept. Therefore after inputting the slope and y-intercept we should get y = -2x + 2
