Question

Can you help me with the fourth one marked as e

Answer 1

we have the equatiion

4x-5y=20

Convert to slope intercept form

y=mx+b

so

Isolate the variable y

step 1

subtract 4x both sides

4x-5y-4x=4x+20

simplify

-5y=-4x+20

step 2

Divide both sides by -5

so

-5y/-5=(-4x+20)/-5

simplify

y=(4/5)x-4
