x isn't a linear equation, it's just a variable or an expression or a letter of the alphabet.
x = 0 is a linear equation and is a line in the Cartesian plane. In fact, it's the y axis itself.
So every point on the line x=0 is a y intercept.
There is no "the" y intercept, no unique y intercept.
Answer:
(7,4)
Step-by-step explanation:
midpoint formula (x1+x2)/2 , (y1+y2)/2
Look at x and y for the endpoints separately
midpoint x value = ( 1 + x)/2
4= (1 + x)/2
8 = 1 + x
x = 7
midpoint y value = (2 + y)/2
3 = (2 + y)/2
6 = 2 + y
y = 4
endpoint (x,y) = (7,4)
Well 15 is over 8 so figure out how many times 8 goes into 15 then the rest of 15 replaces it over the 8
Do you have a picture or sum?
