Answer:
k12
Step-by-step explanation:
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
Answer:
y = 3x - 11
Step-by-step explanation:
y=mx+b
1=3(4)+b
1=12+b
b=-11

Step-by-step explanation:
Answer:16 weeks
Step-by-step explanation:Since we know Sam can make 20 paintings in 4 weeks we must add the weeks
8 weeks will be 40 paintings
12 weeks will be 60 paintings
16 weeks will be 80 paintings
Hence the answer is 16 weeks to create 80 paintings
