Answer: -159
Step-by-step explanation:
Y=mx+b where m=slope=(dy/dx) and b=y-intercept (value of y when x=0)
You have two points...(1,-2),(3,2) so
m=(y2-y1)/(x2-x1)=(2--2)/(3-1)
m=4/2=2 now that you have the slope...
y=2x+b, you can use either point to solve for the y-intercept, I'll use (3,2)
2=2(3)+b
2=6+b
b=-4 so the line is:
y=2x-4
Answer:
1: 37.5%
2: C.p= 12×25= 300
S.p= 12×28= 336
profit%=336-300×100/300=12% ansr..
3: Therefore, Mr. Arsalan sold the plot at Rs 129600.

BRO HOPE IT HELPED I COULDN'T WRITE ON PAPER, SORRY FOR THAT...
Hello from MrBillDoesMath!
Answer:
y = x/15
Discussion:
Given:
2x/5y = 6 => (multiply both sides by 5y)
(2x/5y) 5y = 6 * (5y) =>
2x = 30y => (divide both sides by 30)
(2/30)x = y =>
y = x/15
( or you could also multiply both sides of the original equation by "y" and then divide both sides by 6)
Thank you,
MrB
