Question 1
Graph y=15x+3.

Question 2
Identify the x-intercept

X-intercept: (-0.2,0)

Step-by-step explanation:

y=15x+3

I don't know how to show a graph but what you do is start by plotting (0,3) and go up 15 and over 1 to form a line (because the slope is 15).

To find the x-intercept, replace y with 0 and solve for x.

0=15x+3

-3=15x

-3/15

-1/5 (or -0.2)

(-0.2,0)

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
