Use technology to find points and then graph the line y=-5(x-5)+1 following the instructions below.
Svetach [21]

Given:

y=-5(x-5)+1

First, let us find two points from this equation.

We can set values of x and then solve for y.

Let us find the values of y when x = 1, 2, 3, 4, 5

\begin{gathered} y=-5(x-5)+1 \\ y=-5(1-5)+1=21 \\ y=-5(2-5)+1=16 \\ y=-5(3-5)+1=11 \\ y=-5(4-5)+1=6 \\ y=-5(5-5)+1=1 \end{gathered}

We now have a set of points:

(1, 21)

(2, 16)

(3, 11)

(4, 6)

(5, 1)

Since the given plane is limited to values of 10 and -10, the points that we can plot are the points (4, 6) and (5, 1)

The graph would then look like this:

Solve :<br><br> 5x - 7y = 12<br><br> 5y - 2x = - 7
Afina-wow [57]
There is one solution:

use elimination method

5x - 7y = 12
5y - 2x = -7    ---> change equation around

 5x - 7y = 12
-2x + 5y = -7

2 x ( 5x - 7y) = 2 x (12)    multiply both sides by 2
5 x (-2x +5y) = 5 x (-7)

this give you
 10x - 14y =24 
-10x+25y = -35                    add down
-----------------------------
        11y = - 11                    x is eliminated to find y value
           
            y = -1                         input to one of the original equations

5(-1)  - 2x = -7

-5  - 2x = -7
+5           +5                       add 5 to both sides
----------------------------
-2x = -2
    x = 1

your coordinates for when they intersect is at (1, -1)
one solution
