How do you get the slope and y intercept for this problem?
a) y = - 2x + 1
How about this one?
b) y = x + 6

In a linear equation of the form y = mx + b, m is the slope and b is the y-intercept. So, looking at A), m = -2 and b = 1, so the slope is -2 and the y-intercept is 1. For B), m = 1 and b = 6.

when you have the equation of a line expressed as "y=mx+b" then "m" is the slope and "b" is the y-intercept. So
(a) m = -2, b = 1
(b) m = 1, b = 6

slope intercept form is y=mx+b.
m = the slope (always the number before x)
and
b = the y-intercept
So... in the first problem, the slope is -2 and the y-intercept is 1.
In the second problem, the slope is 1, since there is no number in front of the x it is understood to be a one, and the y-intercept is 6.
