write the equation of the line with slope 2 that passes through the point (-1,5)
- Math - Jai, Wednesday, May 23, 2012 at 11:35pm
recall slope-point form:
y - y1 = m(x - x1)
m = slope
(x1, y1) = point on the line
y - 5 = 2(x - (-1))
y = 2(x + 1) + 5
y = 2x + 2 + 5
y = 2x + 7
hope this helps` :)

write y-3=-5(x+1) in slope-intercept form ?
- Math - Jai, Wednesday, May 23, 2012 at 11:40pm
Note that slope-intercept form is in the form
y = mx + b
m = slope
b = y-intercept
y - 3 = -5(x + 1)
y = -5x - 5 + 3
y = -5x - 2
