Answer:
answer 1/2
Step-by-step explanation:
y-3=-2(x-4)
y-3=-2x+8
y=-2x+11
y=mx+c
m= slope which is -2
because it perpendicular It became 1/2
Answer:
B. c= -c+2
Step-by-step explanation:
A. ...................
It has infinitely many solutions as the equation is correct for any value of c.
B. ...................
- c= -c+2
- c+c= 2
- 2c = 2
- c = 2/2
- c= 1
It has one solution only
C. ...................
- c+2=c-2
- c-c= -2 - 2
- 0 = -4
It has no solution as this equation is incorrect
D. ...................
It has no solution as this equation is incorrect
Answer:
B
Step-by-step explanation:
• A line sloping upwards from left to right has a positive slope
• A line sloping downwards from left to right has a negative slope
The line shown here slopes downwards from left to right, hence has a negative slope → B
