Answer:
-1
Step-by-step explanation:
we would use the slope formula which is y2-y2/x2-x1
so 3-4/5-4= -1
The answer to your problem is 11
Answer:
21
Step-by-step explanation:
You replace the y with f(x)
So it becomes f(x)=2x+1
X intercept: when y = 0
y intercept: when x = 0
Plug info inside the equation
3x + 7(0) = 42
3x = 42, x = 14
Therefore, x intercept: (14,0)
3(0) + 7y = 42
7y = 42, y = 6
Therefore, y intercept: (0,6)
