Answer:
The system of equations are;
3x + 2y = 170
4x +6y = 360
Step-by-step explanation:
Form simultaneous equations and solve
Let x=price of children tickets
Let y=price of adult tickets
The Brown Family paid $170 for 3 children and 2 adults , this forms the equation as:
3x + 2y =$ 170
3x + 2y = 170 --------------------------equation (i)
The Peckham Family paid $360 for 4 children and 6 adults.
4x + 6y = $360
4x +6y = 360 ---------------------------equation (ii)
Solving the equations by graph will give value of x=30 and y=40
The price of children tickets was $30 and that of adults was $40

Answer:
5/4
Step-by-step explanation:
The slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (9 -4)/(7 -3) = 5/4
The slope of the line through those points is 5/4.
_____
The attached graph shows the equation of the line in point-slope form, so you can see that the computed slope makes the line go through both points.
