Answer:
I have wrote just answers
The answer is y = 2x + 3.
x - Kay's age
y - Jane's age
m - Mary's age
<span>Jane is 3 years older than Mary: y = m + 3
</span><span>Mary is twice as old as Kay: m = 2x
</span><span>
y = m + 3
m = 2x
Substitute m in the first equation:
y = 2x + 3
</span>
5) slope is y=mx+b
3) cross the y-axis
1) perpedicular to the y-axis
4) parallel
sorry it's in a random order and idk #2
