Answer:
1). y = -4/7x 2). y = 7/4x - 65/4
Step-by-step explanation:
1). When a line is parallel, the slope remains the same.
y = -4/7x + b
-4 = -4/7(7) + b
-4 = -4 + b
0 = b
The equation is simply y = -4/7x.
2). When a line is perpendicular, the slope becomes the exact opposite.
y = 7/4x + b
-4 = 7/4(7) + b
-4 = 49/4 + b
-65/4 = b
The equation is y = 7/4x - 65/4.
Given :
Andrew has already played 32 minutes on his video game this morning and wants to play an additional 15 minutes on each of x games after school today.
To Find :
Which equation can be used to find y, the total minutes Andrew will play video games today.
Solution :
Number of minutes he play after school time, n = 15x .
Number of minutes already played, c = 32 .
So, total number of minutes he play games for today is :
y = n + c
y = 15x + 32
Therefore, equation which is useful to find number of minutes video game played per day is y = 15x + 32 .
