-84 = 3(5n + 2)
Multiply everything in the parenthesis.
-84 = 3(5n + 2)
3*5n + 3*2
-84 = 15n + 6
Subtract 6 from both sides
-84 = 15n + 6
-6 -6
-90 = 15n
Divide 15 from both sides
-90 = 15n
--------------
15 15
-6 = n
-6 is your answer.
#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)
