Step-by-step explanation:
Answer:
(4,-5)
Step-by-step explanation:
You can use substitution to substitute the answer options in for x and y or substitute an equation in to find each variable.
Substitute an equation is the traditional method and will allow you to solve without any answer options.
1. Substitute y=x - 9 into 3x+2y=2.
3x+2(x-9) = 2
3x+2x-18=2
5x-18=2
5x=20
x=4
2. Substitute x=4 into y=x-9.
y = 4-9
y=-5
(4,-5) is the solution.
Y = mx + b is the format for this equation, where <em>m</em> is the slope and <em>b</em> is the y-intercept. with that information, (-1) would be your slope, taking the assumed coefficient of 1 from the x, and the y-intercept is 5.
