Step-by-step explanation:

4-2 = 2, which is the slope, meaning for every one over on the x axis the number increases by 2,

2 x 2 = 4, 4 + 6 = 10,

salso 14 - 10 = 4, which since 2 + 2 equals 4, and 2 times 2 equals 4, the answer to this equasion  is y=2x+6

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
