The equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.
<h3>What is the equation of a line passing through two given points in a 2-dimensional plane?</h3>
Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by
The graph of the picture shows two clear points (4.5. 0) and (0, 9)
Hence, the equation of line passing through points (4.5. 0) and (0, 9) is y = -2x + 9.

Hello!
To solve this problem, we will use a system of equations. We will have one number be x and the other y. We will use substitutions to solve for each variable.
x+y=9
x=2y-9
To solve for the two numbers, we need to solve the top equation. The second equation shows that x=2y-9. In the first equation, we can replace 2y-9 for x and solve.
2y-9+y=9
3y-9=9
3y=18
y=6
We now know the value of y. Now we need to find x. We can plug in 6 for y in the second equation to find x.
x=2·6-9
x=12-9
x=3
Just to check, we will plug these two numbers into the first equation.
3+6=9
9=9
Our two numbers are three and six.
I hope this helps!
Answer:
60
Step-by-step explanation:
x + 0.30x = 78
