Answer:
slope = 2
Step-by-step explanation:
Pick two points to find the slope. (1, 2) and (3, 3)
From the left (1, 2) to (3, 3), it goes up 2 units and to the right 1 unit.
We can plug this into the slope equation which is rise/run
2/1 = 2 = slope
Answer:
6
Step-by-step explanation:
2 times the difference of a number and 1 = 4 plus that number
In other to express the word problem Mathematically ; let the number = x
2(x - 1) = 4 + x
Expand
2x - 2 = 4 + x
Collect like terms
2x - x = 4 + 2
x = 6
Hence, the number is 6
