What is the equation if slope is -2, y intercept is 1

Question

It's a multiple choice question, either y=2x-1 or y=1/2-1

Answer 1

Neither choice is correct. The correct slope-intercept form for this problem is y = -2x + 1

Answer 2

Hi James G

In the equations you have listed are there a typos of some kind? If you line your equations up against the Slope Intercept Form of a line y = mx +b where m is the slope and b is the y intercept, none answer the question

y = mx + b

y = 2x - 1

In the equation above, m = 2 and b = -1

For the next one

y = mx + b

y = 1/2 - 1

The x is missing.

Did you mean y = -2x + 1 or y = 1/2x + 1?
