Answer:
B. 7/18
Step-by-step explanation:
(-1/6)/(-3/7)
= -1/6 * -7/3
= -1*-7/6*3
= 7/18
(pls give brainliest)
I would say that the answer is B. First because the line AB is descending from left to right which shows that it is negative. Secondly, the gradient 3 would be steep and the gradient 1/3 would not be as steep which is why iI would say it is 1/3. Overall, the answer would be negative and 1/3 which would be B.
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1)
-2/2
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b"
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b
4 = 1 +b
4-1 = b
3 = b
So your equation is:
y = -1x + 3 or y = -x + 3

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -2x + 9
y = 3x + 9
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 3x + 9 = -2x + 9
- [Addition Property of Equality] Add 2x on both sides: 5x + 9 = 9
- [Subtraction Property of Equality] Subtract 9 on both sides: 5x = 0
- [Division Property of Equality] Divide 5 on both sides: x = 0
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -2x + 9
- Substitute in <em>x</em>: y = -2(0) + 9
- Multiply: y = 0 + 9
- Add: y = 9
