Answer:
10
Step-by-step explanation:
To find the slope subtract the points like the following:
(-27-(-7)/(-2-0)
= -20/-2
=10
So, the slope is 10.

Answer:
a=-26,b=-10,c=-1,d=-2
Step-by-step explanation:
when x=-3
y=-(-3)^2 +4(-3)-5=a
a=-9-12-5
=-14-12
=-26
when x=-1
y=-(-1)^2 +4(-1)-5=b
=-1-4-5
b=-10
when x=2
y=-(2)^2 +4(2)-5=c
=-4+8-5
=-9+8
c=-1
when x=3
y=-(3)^2 +4(3)-5=d
=-9+12-5
=-14+12
d=-2
Answer:
(1, 2) is not a solution
Step-by-step explanation:
To determine if the point is a solution substitute the coordinates into the left side of both equations and if equal to the right side then the point is a solution.
- (3 × 1) - 2 = - 3 - 2 = - 5 ≠ 18
(5 × 1) + (6 × 2) = 5 + 12 = 17 ≠ - 12
Hence (1, 2) is not a solution of the system of equations
