Which value of y would make OP || LN ?

Remark
All you need do is assume the small triangle is similar to the large one. MO:ML :: MP:MN must be solved.

Givens
MO = 28
ML = 28 + 14
MP = y
MN = y + 18

Equation
28:28+14 :: y: y + 18

Solve
28/42 = y / (y + 18)
28*(y + 18) = 42y        Remove the brackets
28y + 18*28 = 42y
28y + 504 =  42y         Subtract 28y from both sides.
504 = 42y - 28y
504 = 14y                    Divide by 14
504/14 = y
y = 36

Use the domain {-1, 0, 1, 2, 3, 4} and plot the points on the graph that would best satisfy the equation y = 2x.
Dmitrij [34]
Domain is ur x values

y = 2x...when x = -1
y = 2(-1)
y = -2.....(-1,2) satisfies this equation

y = 2x....when x = 0
y = 2(0)
y = 0....(0,0) satisfies it

y = 2x....when x = 1
y = 2(1)
y = 2....so (1,2) satisfies it

y = 2x....when x = 2
y = 2(2)
y = 4....(2,4) satisfies it

y = 2x...when x = 3
y = 2(3)
y = 6.....(3,6) satisfies it

y = 2x...when x = 4
y = 2(4)
y = 8.....(4,8) satisfies it
