Answer:
14.56
Step-by-step explanation:
3x+y=15
First convert the equation into slope intercept form. y=mx+b
Where m is the slope and b is the y-intercept.
3x+y=15
Subtract 3x from both sides
y=-3x+15
Here slope, m=-3
Answer: Slope is -3. Option C is correct
Answer:
0
Step-by-step explanation:
y = 6x + 6
y = 6x - 12
Because both equations are equal to y, we can set them equal to each other, resulting in
6x + 6 = 6x - 12
Subtract 6x from both sides to eliminate the x values
6 = -12
This is impossible, so there are no solutions.
