y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)
1. slope: -3
y-intercept: 7
y = -3x + 7
Your answer is B
y + 3x = 7 Subtract 3x on both sides
y = -3x + 7
2. y + 9(x + 3) = 0 Multiply/distribute 9 into (x + 3)
y + 9x + 27 = 0 Subtract 9x and 27 on both sides to get "y" by itself
y = -9x - 27
slope: -9
y-intercept: -27 or (0,-27)
Your answer is D
3. Point-slope form: y - y₁ = m(x - x₁)
slope: -11
(x₁ , y₁) = (-5, 7)
y - 7 = -11(x - (-5)) The two negative signs becomes a positive
y - 7 = -11(x + 5)
Your answer is C
4. For this question, I think you get it from point-slope form to slope-intercept form (I'm not sure, but you still get the same answer if you just do slope-intercept form)
slope: -4
(x₁ , y₁) = (2, -8)
y - y₁ = m(x - x₁)
y - (-8) = -4(x - 2)
y + 8 = -4(x - 2) Multiply/distribute -4 into (x - 2)
y + 8 = -4x + 8 Subtract 8 on both sides to get "y" by itself
y = -4x
Your answer is A
Answer:
In example when talking about some supply, half of it was sold or three fifths of what was there is gone. Fractions are a natural way of talking about sub unit quantities or just rationing supplies.
Answer:
5
Step-by-step explanation:
We know that Karen divided her garden into equal parts of which she intend to plant corn in ⁸/20 of it.
This implies that she divide the garden was divided into 20 parts.
To determine the fewer number of parts she can divide her garden into, simply ⁸/20.
Thus:
8/20 = (2*4)/(5*4)
= ²/5 (4 cancels out 4)
Therefore, this implies that the least number of parts she can divide her garden into is 5.
Answer: a.5
Step-by-step explanation: You cross multiply and get 2x=5x-15. You then simplify this, getting -3x=-15. So the answer is 5.
Answer:
y = -8x + 4
Step-by-step explanation:
In slope intercept form, y = mx + b, the slope is m and the y intercept is b.
Substitute -8 for m and 4 for b.
hope this helps :)
