How would use solve this using point-slope form? The answer needs to be in slope-intercept form though. 

 

Line c has an equation of y = -8x + 3. Line d includes the point (-1, -2) and is parallel to line c. What is the equation of line d?

Line c slope = -8     parallel slope of new line = -8 also

 

y= -8x + b      Must include point -1,-2     sub this in to the equation to find 'b'

-2 =-8(-1) + b

-10 = b

 

y = -8x - 10    === line d
