Question

Which function will start at the origin (0,0), when graphed? A. y=x+8 B. y=x+4 C y=8x D. y=x-5

Answer 1

C

Explanation:

The general equation of a line is;

y = mx + c

where m is the slope and c is the y-intercept

All the lines except y = 8x have a y intercept

Since it does not have the y-intercept, it is expected that the plot starts at the origin
