Answer: y = 4x + 20

Step-by-step explanation:

4x - y = -20

=> -y = -4x - 20

=> y = 4x + 20

Answer:

4x - y = - 20 in y=mx+b form is:  y = 4x + 20

Step-by-step explanation:

Given the equation

[tex]4x - y = - 20[/tex]

What is the slope-intercept form of linear/line function?

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

  • [tex]m[/tex] represents the slope
  • [tex]b[/tex] represents the y-intercept

Converting the equation into the slope-intercept form of the line equation

[tex]4x - y = - 20[/tex]

Add -4x to both sides

[tex]4x-y+\left(-4x\right)=-20+\left(-4x\right)[/tex]

simplify

[tex]-y=-20-4x[/tex]

Divide both sides by -1

[tex]\frac{-y}{-1}=-\frac{20}{-1}-\frac{4x}{-1}[/tex]

Simplify

[tex]y=4x+20[/tex]

Therefore, 4x - y = - 20 in y=mx+b form is:  y = 4x + 20
