Answer:
Find answers below.
Step-by-step explanation:
The equation isn't explicitly stated or well written. Thus, we would assume two (2) case scenario for the equation of line by altering the signs.
Scenario 1;
y = 9 + x
Mathematically, the equation of a line is given by the formula;
Equation of straight line is y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Comparing the two equations, we have;
y = mx + c = 9 + x
Constant, c = 9
Slope, m = 1
Scenario 2.
y = 9 - x
y = mx + c = 9 - x
Constant, c = 9
Slope, m = -1
