Answer:
Option D
Step-by-step explanation:
A horizontal line has no slope. The equation 'y=1' graphs as a horizontal line. It passes (0,1). So, it touches the y-axis.
A line with an undefined slope does not touch the y-axis. It is vertical.
Option D should be the correct answer.

Answer:
52
Step-by-step explanation:
Total Number of students :
Stage 3 : 380
Stage 4 : 240
Stage 5 : 110
Total = (380 + 240 + 110) = 730
Number of samples required = 100
Number of key stage 3 students required :
(Key stage 3 / total) * number of samples
(380 / 730) * 100
= 0.5205479 * 100
= 52.0547
= 52
It is substitution. Because you are substituting 3=y into x+5=3
