Answer:
A(2/9, 1/3)
B(2/3, -1/3)
slope = -1.5
Step-by-step explanation:
A graph can show the coordinates of interest: A(2/9, 1/3); B(2/3, -1/3).
Rearranging the equation to slope-intercept form, we have ...
3y = -4.5x +2
y = -1.5x +2/3
The slope is -1.5.
Answer:
y = 
x - 5
y = 2x + 5
Step-by-step explanation:
In linear equations, both variables x and y must have the exponent of 1 (i.e. they cannot have a small number at the top-right). And they cannot be in the exponents (i.e. cannot be the small number at the top-right).
Step-by-step explanation:
For the point (5,8) to be a solution to the equations, when you insert x=5 and y=8 , they have to equal to the given values
substituting (5,8) into 4x+y
4(5)+8
=20+8
=28
substituting(5,8) into x-y=3
5-8
= -3
