First rewrite the equation in slope intercept form

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

[tex]\rightarrow \sf 8y = -2x+32[/tex]

[tex]\rightarrow \sf y =\dfrac{ -2x+32}{ 8}[/tex]

[tex]\rightarrow \sf y =\dfrac{ -2x}{ 8} + \dfrac{32}{8}[/tex]

[tex]\rightarrow \sf y =\dfrac{ -1}{ 4}x + 4[/tex]

comparing with y = mx + b

  • slope: -1/4     and   y-intercept: 4

x-intercept:          ( then y will be 0 )

[tex]\hookrightarrow \sf -2x + 32 = 0[/tex]

[tex]\hookrightarrow \sf -2x = -32[/tex]

[tex]\hookrightarrow \sf x = 16[/tex]

In order to graph the line

  • plot x = 16 on the x-axis     coordinate: (16, 0)
  • plot y = 4 on the y-axis     coordinate: (0, 4)
  • Then using a scale/ruler draw a straight line through this points.

Graph:

  • 8y=-2x+32
  • 4y=-x+16
  • y=-1/4x+4

Compare to slope intercept form

  • slope=m=-1/4
