(-4,5)(3,-9)
slope = (-9 - 5) / (3 - (-4) = -14 / (3 + 4) = -14/7 = -2
y = mx + b
slope(m) = -2
use either of ur points...(-4,5)...x = -4 and y = 5
now we sub and find b, the y int
5 = -2(-4) + b
5 = 8 + b
5 - 8 = b
-3 = b
so ur equation is : y = -2x + (-3) which can be written as : y = -2x - 3
Answer:
A. Measure of angle 2 + measure of angle 3
Step-by-step explanation:
Because angle 4 is an exterior angle of given triangle which will be equal to the Measure of angle 2 + measure of angle 3
Answer:
Step-by-step explanation:
x + y = -20......multiply by -6
6x - 5y = -20
-----------------
-6x - 6y = 120 (result of multiplying by -6)
6x - 5y = -20
---------------add
-11y = 100
y = -100/11 <======
x + y = -20
x + (-100/11) = -20
x - 100/11 = -20
x = -20 + 100/11
x = -220/11 + 100/11
x = - 120/11 <========
solution is : x = -100/11 and y = -120/11 or (-120/11 , -100/11)
6a^2x-10 beccause u have to multiply
