**Answer:**

Three solutions.

**Step-by-step explanation:**

In order to solve system of equations by graphical method, we graph the system of equations. **The intersection point (s) of the two graph would give us the solution. **

If the graph of the equations intersect at 2 points then there will be 2 solutions, if there are 4 intersection then there would be 4 solutions and so on.

For the given graph, we can see that there are three intersection points.

**Hence, there would be three solutions. **

The first thing you want to do is figure out what the slope of line is.

the slope of a line in the format Ax+By=C is -A/B

so the slope of the line 2x+10y=20 is -2/10 which simplifies to -1/5

now that you know the slope of that line (i’ll call it line 1), you can use it to find the slope of the perpendicular line by taking the opposite reciprocal of the slope of line 1

slope of line 1: -1/5

opposite reciprocal of the slope of line 1 (which is the perpendicular line’s slope): 5

and since you now have a slope and a point, you can use point-slope [y-y₁=m(x-x₁)] form to write the equation of the line

m = 5

point (x₁y₁): (2,3)

point slope form:

y-(3)=(5)(x-(2))

y-3=5(x-2)

to slope intercept form

y=5x-10+3

y=5x-7

hope this helps :)
