Does the point (2 , 3) lie on the line y = 4x -5 ? Bonus = Does the point (-1 , 17) lie on the line y= 18 + 2x ?

Question 1:

Point = (x,y) = (2,3)

So, x = 2, y = 3

Let's put this in the equation to check whether it lies on the line or not

=> 3 = 4(2)-5

=> 3 = 8-5

=> 3 = 3

Since LHS = RHS so The point lies on the line

Question 2:

Point = (x,y) = (-1,17)

So, x = -1, y = 17

Let's put this in the equation to check whether it lies on the line or not

=> 17 = 18+2(-1)

=> 17 = 18-2

=> 17 ≠ 16

Since LHS ≠ RHS, So this point doesn't lie on the line.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
