gradient or slope=<u>y2 -y1</u>
x2 - x1
so for A, p is x1 and 3 is y1..
For B, 6 is x2 and p is y2
2= <u>p - 3</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>6 - p
2 ( 6 - p) = p - 3
12 - 2p = p - 3
-2p + p = -3 - 12
-p = - 15
p = 15
A) The Y-intercept of this equation is 3
B) The slope of this equation is 2
C) This equation has a positive slope
D) Starting from the Y-intercept, I simply went over to the right 1 box, and up 2 boxes
I hope this helps!
For the first one it is x= (y+3)/4
Gcd(3,2)=1 Hope this helps!!
(The answer is 1)
