5p - 3q = -39
- (-2p - 3q = 3)
==> 7p = -42 ==> p = -6

==> p = -6
-2(-6) - 3q = 3 ==> 12 - 3q = 3

==>p = -6
-3q = 3 - 12 ==> -3q = -9

==> p = -6
q = 3

What is the slope and the point of y - 5 = 3/2 (x + 3)? please help

goldfiish [28.3K]

y - 5 = 3/2(x + 3)

y - 5 = 3/2x + 9/2

y = 3/2x + 9/2 + 5

y = 3/2x + 19/2

Equation of the line formula : y = mx + c

#So the slope (m) is 3/2
