Answer:

y=-x+1

Step-by-step explanation:

to get this you use the point-slope formula

y-y1=m(x-x1) - plug in the coordinates and find the slope

y--3=-1(x-4) - change the sign and solve the parentheses

y+3=-x+4 - subtract 3 from both sides to get y by itself

y=-x+1

How to convert improper fraction to mixed numbers
MakcuM [25]

Answer:

Step-by-step explanation:This is an improper fraction: 243/10 to convert it to a mixed number just do 243 divided by 10 which equals 24, so put that number as a whole number in front of the fraction, then do 24 times 10 which equals 240, then since 240 is 3 less than 243 the answer is 24 and 3/10.

If you need, I can try to explain it better.
