#4
(-2,4)(-3,5)
slope = (5-4)/(-3+2) = 1/-1 = -1
point slope form
<span>y-y1 = m(x - x1)
</span>y - 4 = -(x + 2)
#5
y intercept of 3 , y = 3 or (0,3)
x intercept of -2 , x = - 2 or (-2,0)
slope = -3/2
slope intercept form
y = mx + b
y = -3/2x + 3
#6
point slope form
y = 1/2x - 4 passing thru(5,2)
y - 2 = 1/2 (x - 5)
# 7
y = 1/2x - 4
perpendicular slope = -2
passing thru (-1,4)
using point slope form
y-4 = -2(x+1)
Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
