Y = mx + b
where m is the slope and b is the y-intercept.
1. 2x + 3y = 12
3y = -2x + 12
y = -2x + 4
y-intercept is 4
2. x - 4y = 20
-4y = -x + 20
y = -x - 5
y-intercept is 5
3. y = 2x - 9
this one is easy because it's already in standard form
y-intercept is -9
Answer:
15 ≤ x - 10
Well, that's how you describe it, and I write it for you.
Straight
Never ending (You can tell this as there are arrows on the ends)
On a diagonal with a negative slope
1,000 pounds 200 ounces
25,000 ounces
16,500 pounds
7 tons 200 pounds 100 ounces
X^2/a^2+y^2/b^2=1
a^2=100 a=10
b^2=64 b=8
c^2=a^2-b^2
c=6
