Answer:

Step-by-step explanation:
we have the points
(0,-3),(2,0) and (4,3)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
we take
(0,-3),(2,0)
substitute the values in the formula
step 2
Find the equation of the line in slope intercept form

we have
-----> the point (0,-3) is the y-intercept
substitute

The graph in the attached figure
Y *x =20
y +x =9
rewrite 1st eq. as y = 20/x
subsituute that into 2nd eq.
20/x +x =9
multiply each term by X
20 +x^2 = 9x
subtract 9x from each side:
x^2 - 9x +20 = 0
now factor:
(x-5) (x-4) = 0
solve for x
5-5 = 0
4-4 = 0
so X can be 4 or 5
replace x into equations and solve for Y
so when X = 4, Y = 5
When X = 5, Y = 4
x= 5,4
y = 4,5
