y=mx+c
where m is the gradient and c is the y-intercept
Now, find the gradient.
Take,
By substitution,
we now put the values of m, x and y into the general equation to find the c
Hence the y-intercept of the line is 32
Find cost of pens and mechanical pencils
pen cost=number of pens times cost pe pen
pencost=10 times 0.35=3.50
mech cost=number of mechs times cost pe mech
mechcost=5 times 0.89=4.45
4.45 is more than 3.50
yes, mech cost mre than pens
