Answer: 0 - 4
Step-by-step explanation:
0 - 4 = -4
-3 + 4 = 1
1 - 5 = -4
Hello,
Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2
Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4
One other way:
y=9-1/2 x²
y'=-x
gradient 1=-(-2)=2 for point (-2,7)
gradient 2=-(4)=-4 for point(4,1)
2x + 6y = 12
6y = -2x + 12
y = -2x/6 + 12/6
y = -1/3 x + 2
