Let us say "y" coordinate represents number of movies and "x" coordinate represents number of months.
Movies watched in 1st month = 6
so we can say first ordered pair is (1,6)
Movies watched in 2nd month =6
so we can say second ordered pair is (2,6)
Now we have two points here (1,6) and (2,6)
We can use formula for slope as :
slope = 0
The slope of a horizontal line. A horizontal line has slope 0 because all its points have the same y-coordinate. As a result, the formula used for slope evaluates to 0.
The graph is shown here:
The equation of graph would be y=6.
The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
1/3x because the slope have the opposite reciprocal of -3x
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
