Question

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

Answer 1

Answer: y = 4x + 20

Step-by-step explanation:

4x - y = -20

=> -y = -4x - 20

=> y = 4x + 20

Answer 2

Answer:

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

Step-by-step explanation:

Given the equation

$4x - y = - 20$

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

The slope-intercept form of the line equation

$y = mx+b$

where

• $m$ represents the slope

• $b$ represents the y-intercept

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

$4x - y = - 20$

Add -4x to both sides

$4x-y+\left(-4x\right)=-20+\left(-4x\right)$

simplify

$-y=-20-4x$

Divide both sides by -1

$\frac{-y}{-1}=-\frac{20}{-1}-\frac{4x}{-1}$

Simplify

$y=4x+20$

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