X - 2y equals -1 and 2x - y equals 4?

(3, 2)


What type of lines are these y equals 2x plus 4 and 12 equals 2y plus x?

If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines

Use the substitution method to solve the system of equations Enter your answer as an ordered pair 16x - 2y equals 74 2x - 2y equals 4?

16x - 2y = 74 (Eq 1) 2x - 2y = 4 (Eq 2) from Eq 2, 2y = 2x - 4 Substitute in Eq 1 16x - (2x - 4) =74 ie 16x - 2x + 4 = 74 ie 14x = 70 ie x = 5 2y = 2x - 4 = 10 - 4 = 6 y =3 Check 16 x 5 - 2 x 3 = 80 - 6 = 84 QED


What is -2x plus 2y equals 4?

-2x + 2y = 4 is equivalent to twice -2 + y = 2 which is the equation of a straight line.


How do you find y intercept for -2x plus 2y equals 4?

-2X + 2Y = 4 2Y = 2X + 4 Y = X +2 by inspection, 2 but, you could also 0 out X in original equation -2(0) + 2Y = 4 2Y = 4 Y = 2


Is point 1 4 on the line represented by the equation x plus 2y equals 5?

The equation "x plus 2y equals 5" is: x + 2y = 5 2y = 5 - x y = 5/2 - 1/2x y = -1/2x + 5/2
