Write equations for the vertical and horizontal lines passing through the point (8,-9)

x = 8 and y = - 9

Step-by-step explanation:

The equation of a vertical line is x = c

Where c is the value of the x- coordinates the line passes through

The line passes through (8, - 9) with an x- coordinate of 8, thus

Equation of vertical line is x = 8

The equation of a horizontal line is y = c

Where c is the value of the y- coordinates the line passes through

The line passes through (8, - 9) with y- coordinate - 9, thus

The equation of the horizontal line is y = - 9

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
