6 wore blue + 5 wore green + 3 wore black = 14
If there are a total of 18 total students, then the number of people who wore other colored shirts is 4 because 18-14= 4. Therefore, 4/14, which is 2/7 simplified, represents the students who did not wear blue, green or black.
Answer:
y=3x+1
Step-by-step explanation:
Your equation should start off as y=mx+b. You must solve for m and b, although they already give you m and b. m is the slope, which here is 3 and your y is 1. Making your equation, y=3x+1.
