Answer:
y=10,x=6
STEP BY STEP EXPLANATION
When x=6
substitute x=6 in equation
y=6+4
y=10
when y=5
substitute y=5 in equation
5=x+4
5-4=x
x=1
Answer:
z = x-1
Step-by-step explanation:
Observe first that the slope of y is 1*x (the one is omitted). Therefore, any line parallel to y must have the same slope. We know there's a line, let's call it z = x + m (for some value m), parallel to y that passes through the point (6, 5) where 6 is the value of x and 5 is the value of z. Inserting these values into the expression z = 1*x + m we get an equation that we can solve for m.
[tex]5 = 1*6 + m \implies\\5 = 6 + m \implies\\5 - 6 = 6 - 6 + m \implies\\-1 = m[/tex]
Using m = -1 in our equation for z = 1*x + m we get z = x-1.
Note that z is just an arbitrarily chosen variable to replace y. You may use a, b, y or any letter but I use z here to avoid confusion with the original expression.
