Answer:
A (a = 1)
Step-by-step explanation:
A coordinate point is always in the form (x,y) that means the first point is always x-coordinate and the second point is always y-coordinate.
The equation given is:
5x + y = 8
The point is (a,3), so that means x = a and y = 3
We substitute the values into the equation and find a. Shown below:
5x + y = 8
5(a) + (3) = 8
5a + 3 = 8
5a = 8 - 3
5a = 5
a = 5/5
a = 1
Answer choice A is right
Irrational numbers
hope this helped :)
A vertical line has an undefined slope.
vertical lines are X= something
in this case it needs to intercept 9.
so it is X=9
