Answer:
The equation of the line will be:
Step-by-step explanation:
Given the points
Finding the slope between (3, 4) and (12, 9)
The equation of the line can be obtained using the point-slope form of the equation of the line
substituting the values m = 5/9 and the point (3, 4)
Therefore, the equation of the line will be:
Write the 2 equations:
5x-2y=18
-5x+3y=-22
You can see that the coefficients of x are opposites, so you can add them(the 2 equations) to eliminate x.
Adding them, you get:
y=-3
So now that you know y, you can substitute the value of y into one of the original equations. Let's substitute it in the first one:
5x+6=18
Solving this, we get:
5x=12
x=12/5
x=12/5, y=-3
