I don't know what you are looking for
but the equation y = 1/2 x + 7 is called slope intercept form, one of the easiest way to draw line/linear graph.
It has slope(m) of 1/2 and y-intercept (b) of 7.

y= mx + b

Solve the system by graphing:<br> y = x^3 - 4x^2 + x + 3<br> y = 2x - 1
zvonat [6]

Answer:

(-1, -3) and (1, 1)

Step-by-step explanation:

Use a graphing calculator to graph out both lines:

(See picture)

Both lines intersect at points (-1, -3) and (1, 1). These are the solutions for the system of equations.

Since they want only the coordinates of the vertices. You only care about where the lines intersect, the greater than, less than signs are irrelevant.

Get each equation in 'y=mx+b' form
1)  y = -x + 9
2)  y = 2x-21
3)  y = -4x +15

Now you can set any 2 equations equal to each other and solve for 'x'.
This will be the 'x' coordinate of the point where the 2 lines intersect.
You need 3 points, so you will need 3 different sets of 2 equations:

1) = 2)
2x -21 = -x+9
3x = 30
x = 10  -----> y = -(10)+9 = -1


1) = 3)
-x+9 = -4x+15
3x = 6
x = 2  -------> y = -(2) + 9 = 7

2) = 3)
2x - 21 = -4x+15
6x = 36
x = 6  ---------> y = 2(6) -21 = -9

Therefore the 3 intersecting points are:
(10,-1)
(2, 7)
(6, -9)
