Answer: 
Step-by-step explanation:
Slope-intercept form: y=mx+c (i) , of linear equations, m= slope and c= y-intercept of the line.
6x+7y=13in slope intercept form would be :

Comparing to (i) , 
Slope of parallel lines are equal.
So, slope of required line = 
Equation of line with slope m and passes through point : 
So, equation of required line:

Answer:
C: 40 degrees
Step-by-step explanation:
50+2y+y+10=180
60+3y=180
3y=120
y=40
Answer:
10x+23 (pretty sure) and the * means multiply
Step-by-step explanation:

the sides could be 6 cm and 3 cm
the sides could also be 9 cm and 2 cm
the sides could also be 18 cm and 1 cm
Age difference = 15 ÷ 3 = 5
so Caitlin's age is 12 - 5 = 7
