<span>Amelia + Bernard + Cindy = 10w {the total of their ages is 10w}
2w + ? + ? = 10w {Amelia is 2w years old, Bernard and Cindy are the same}
? + ? = 8w {subtracted 2w from each side}
2? = 8w {added ? and ?}
? = 4w {divided each side by 2}
Cindy is 4w
</span><span>If w = 4,
4w
= 4(4){substituted 4 in for w}
= 16 {multiplied}
If w = 4, then Cindy is 16</span>

Step-by-step explanation:
Answer: y=1/2x
Step-by-step explanation:
The equation we can use is slope-intercept form. The formula is y=mx+b. The m represents the slope, and b is the y-intercept. The line passes through the y-axis at (0,0). therefore, the y-intercept is 0.
To find the slope, we can take any two points and use the formula to solve for slope. Let's use (2,1) and (4,2).
The slope is 1/2. Our equation is y=1/2x+0 or y=1/2x.
