Graphing Equations (Algebra)?

Question

Solve each equation for y when the value of x is given.

1) y= 4x - 6; x= 1

2) y= 4x - 2; x= -1

Answer 1

1) y= 4 (4 x 1)
2) y= -4 (4 x -1)

Answer 2

just substitute x in each equation
1.) y=4x-6
y=4(1)-6
y=4-6
y=-2

2.) y=4x-2
y=4(-1)-2
y=-4-2
y=2

Answer 3

1)
y= 4x - 6
Where x= 1;
y = 4(1) -6
= 4 - 6
= -2
ANS: when x = 1 Y = -2
OR
ANS: (1,-2)

2)
y= 4x - 2
Where x= -1;
y = 4(-1) -2
y = -4 -2
y = -6
ANS: when x = -1 Y = -6
OR
ANS: (-1, -6)
