Answer:
x = 2/3
Step-by-step explanation:
3×+4= 6
3x=6-4
3x=3
×=2/3
Test a pair from each table by substituting their values into the given equation and solving.
A) y = 2x + 1 .......... 2 = 2(0) + 1 .......... 2 ≠ 1
B) y = 2x + 1 .......... 1 = 2(0) + 1 .......... 1 = 1
C) y = 2x + 1 .......... -1 = 2(0) + 1 .......... -1 ≠ 1
D) y = 2x + 1 .......... -2 = 2(0) + 1 .......... -2 ≠ 1
The only pair that satisfied the equation was from answer choice B. Therefore, B is the correct answer.
Answer: The slope is 2/3
Step-by-step explanation:
The difference in the rise (y-values) 2, divided by the difference in the run (x-values) 3, is 2/3.
You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)
Using the values of coordinates (3,1) and (0, -1)
1 -(-1) ÷ 3 - 0
2 ÷ 3
2/3
