In summary. The graph of each equation is a straight line, m is the gradient of the line and c is the y-intercept. Conversely, if a straight line has gradient m and y-intercept c it has equation y = mx + c.
Answer:
A.
Step-by-step explanation:
x-2y=4 has a x-intercept of 4, a slope of 1/2, and a y-intercept of -2. 2x+y=4 has a x-intercept of -2, a slope of 2, and a y-intercept of -4.
Correct answer is D.
Use equation of line which passes through the point

Answer:
5/6
Step-by-step explanation:
3/4 is less than 5/6 by ...
5/6 -3/4 = 10/12 -9/12 = 1/12
The number that is greater than 3/4 by 1/2 is ...
3/4 +1/12 = 9/12 +1/12 = 10/12 = 5/6
5/6 is greater than 3/4 by the same amount that 3/4 is less than 5/6.

This is a trick question -- checking to see if you're awake.
If A < B by some amount, then B > A by that same amount.
If B -A = q, then A +q = B.
Answer:
y=3
Step-by-step explanation:
-5y+8=-7
Minus 8 from each side.
-5y=-15
Divide -5 from each side.
y=3
