Y-intercept is the point where the line crosses the y-axis. At this point the the x-component is zero. So the y-intercept is of the form (0,y)
We can see the y-intercept from the given data points. The y-intercept is (0,8) or y=8.
x-axis represents the time spent on reading and y axis represents the time spent on Social Media. The y-intercept indicates that when the time spent on reading is 0, the time spent on Social media is 8 hours.
So, option D gives us the correct answer.
x+y = 90
x=2y+9
2y+9+y=90
3y=81
y= 27 Emily's age
x= 2*27+9 = 63 Matt's age
Answer: $3.18
Step-by-step explanation:
15% off an object means that you could represent the value with the expression '0.85x', since you could imagine x being the full price and x- 15% of x = x-0.15x = 0.85x.
0.85x would equal 2.70. Then you just divide 2.70 by 0.85 to get x, which is 3.18.
