Answer:
$5
Step-by-step explanation:
Just use simultaneous equations to solve this problem.
Let cost of pens = x and cost of pencils = y:
217 x + 131 y = 913
131x + 217y = 827
Solving these 2 equations you get: x = 2 and y = 3
Hence, cost of one pen and one pencil = 2 + 3 = 5 rupees

Answer:
y-17=5(x+2)
Step-by-step explanation:
point slope form is y-y1=m(x-x1)
y1 = y coordinate
m = slope
x1 = x coordinate
so you put in the x and y coordinates from the ordered pair into the equation
