Let’s simply step-by-step.
-9+1/4x-6-1/8x
=-9+1/4x+-6+-1/8 x
COMBINE LIKE TERMS:
=-9+1/4 x + -6 + -1/8 x
=(1/4 x + -1/8 x) + (-9+-6)
Answer
=1/8x -15
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
