Reflect over 
This means that we reflect over the x-axis
And the rule of reflection is:

Hence:

Will become:

So, we have:

Answer:
y = -4x + 19
Step-by-step explanation:
We will use the linear equation y = mx + c for this
m is our slope and c is our offset (y-intercept)
We are informed that our slope is -4 so
y = -4x + c
To find the equation of a line passing through the point (5,-1) we simply plug in our values into our equation
-1 = -4(5) + c
Then we can find c
-1 = -20 + c
19 = c
Now that we have our m and c, we can form an equation of a line that passes through our point:
y = -4x + 19
Answer:
for the line to have a constant slope, the difference of every y- ordinate with the last ordinate has to be equal
to check this, we will use the following formula
y4 - y3 = y2 - y1
if both the LHS and the RHS are equal, the slope is constant and is irregular otherwise
5 - 8 = 7 - 3
-3 = 4
LHS ≠ RHS
Since LHS is not equal to RHS, the slope is NOT constant and hence keeps increasing or decreasing irregularly
Therefore, option 4 (Not a line) is correct
