The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
Answer:
The answer is no solutions.
Step-by-step explanation:
use systems of equations!
first, rewrite both equations so that the sum or difference includes the same variable.
notice how i made sure the coefficients that have x and y respectively line up.
with this, i can cancel out the x variables by making 2, and -4 as -8 (8+-8=0).
rewrite the equation.
distribute.
now we can successfully cancel out the x variable!
uh oh! it seems we can also cancel out the y variables..
18 is not equal to 0 and neither is -16. because of this, we can conclude there is no solution for this system of equations.
hope this helps!!
