Question 71209
{{{y=x}}}
When in the form {{{y=mx + b}}}, m is the slope
For {{{y=x}}}, b = 0, and m = 1
a) A parallel line would have the same slope
as the equation, m=1
b) The slope of a perrendicular line has slope= {{{-(1/m)}}}
{{{-(1/1) = -1}}}
c) By the point-slope formula,
{{{(y - (-3)) / (x - (-2)) = -1}}}
{{{(y+3) / (x+2) = -1}}}
{{{y + 3 = -x - 2}}}
{{{y = -x -5}}}
check this
The slope is -1, as needed. does it go through (-2,-3)?
{{{-3 = -(-2) - 5}}}
{{{-3 = 2 - 5}}}
{{{-3 = -3}}}
OK
Pick any value for x, then find y. Now
you have 2 points and can graph it by hand or computer
