How do you do this problem?

Question

(-1,-1), slope =1

Answer 1

You don't state what you are suppossed to do---so I'll guess. I think they are looking for the equation of the line passing thru (-1,-1), with a slope of 1.

start with the "slope-intercept" format:

y = mx + b , where m is the slope and b is the value of y when x = 0. (Also called the "y intercept)

Plug in the slope of 1 to get:

y = x + b

next, plug in the given values of x and y, and solve for b:

-1 = -1 + b

b = 0
