Question

Part A. Write the equation 5=10x−5y in slope-intercept form.

Part B. Identify the y-intercept.

Answer 1

PART A:

slope intercept form is y=mx + b

5=10x-5y subtract 10 both sides
-10x+5=-5y divide -5 both sides
2x-1=y

slope intercept form is y=2x-1

PART B:

In slope intercept form (y=mx+b), the y intercept is always ‘b’ therefore using the new equation the y intercept= -1

Answer 2

Part A: y=2x-1

Part B: -1
