You can solve the pair of equations graphically by finding where the two lines intersect/meet. The point where they intersect is the solution to both of the equations.
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept, or the point where x = 0 ---> (0 , y))
y = 7x - 9
m = 7
y-intercept = -9 -----> (0, -9)
y = 3x - 1
m = 3
y-intercept = -1 ------> (0, -1)
I'm not really sure what the last sentence of the question is asking, so you could clarify the question if you need help
Answer:
Step-by-step explanation:
Area = 1/2 * 2b * (5b - 7)
Area = 1/2 * 2b * (5b - 7) = 24
b * (5b - 7) = 24
5b^2 - 7b = 24
5b^2 - 7b - 24= 0
(b- 3 )(5b + 8) = 0
b = 3 This the only solution that works. b can't be minus
The base is 2b or 2 * 3 = 6
So the students are on 5:6 ratio from volleyball to football, and we know there are 220 students in total.

Step-by-step explanation:
We have been given 4 points 
. We are asked yo plot these points on coordinate plane and find the area of the figure.
Upon plotting our given points, we will get a rectangle as shown in the attached file.
We can see that the width is 5 units that is difference between y-coordinates of point 
.
We can see that the length of rectangle is 6 units that is difference between x-coordinates of point 
.
We know that area of rectangle is length times width.
Therefore, the area of the figure would be 30 square units.
