slope intercept form is y=MX+b.
M is the slope, x is the x intercept, and b is the y intercept
the slope is
[tex] \frac{ - 2}{1} [/tex]
An intercept is where the formula crosses the axis. therefore, the x intercept is .5, and the y intercept is 1
so the point slope formula is
[tex]y = \frac{ - 2}{1} 0.5 + 1[/tex]
