Question and answer
When we graph the inequality 4x - 3y?_ 0, why can’t we use (0, 0) as a test point? If we test the point (6, -5), do er obtain a false statement or a true one?the number that equation is supposed to
total (6, -5)
(0,0) as a test point can't be use to graph the inequality 4x - 3y because it is prefer to use a solution that is actually possible and (0,0) does makes the solution read 0 > 0 which is false. [ The number that equation is supposed to total (6,-5) is a possible solution so it is a true statement. ]

Obstacles in listening that I have encountered are people who talk extremely fast and you must ask them to repeat part or all of what has been said or asked. Also accents can be tricky, unless you can focus and try to pay attention. Again you have to ask for them to repeat what has been asked or said. Many are understanding and will repeat for you, some become offended. But in order for there to be communication you have to honestly be able to understand the person.

3.1 # 4). (5,1) is a solution to the equation 2x - 3y = 7. What does this mean?
Weegy: FOIL (First Outside Inside Last) = 2x(2x) + 2x(-3y) + (-3y)(2x) + (-3y)(-3y) = 4x^2 + (-6xy) + (-6xy) + (9y^2) = 4x^2 - 12xy + 9y^2 (More)

It means that if we substitute solution (5,1) to the equation 2x - 3y = 7, it would result to a true statement.

2(5) - 3(1) = 7
10 - 3 = 7
7=7, therefore it is correct.

(5,1) is a solution to the equation 2x-3y=7 User: (-3…….) is the solution of y= 4-3x User: Two different lines are parallel if their slopes are
Weegy: Two lines (in the same plane) have the same slope if and only if they're parallel. Somebody said "perpendicular", which is incorrect. Perpendicular lines have slopes that are negative reciprocals of each other. User: Slope of a Line (2,-1) and (6, 3) Weegy: yes it has a slope of -1 User: .Slope of a Line(4,0) and (3.8,2) Weegy: Remember (x, y) (4, 0), (3.8, 2) m = 2 - 0/ 3.8 - 4 m = 2/-0.2 m = -10 User: Slope of a Line( 3, 9) and (7, 15) Weegy: 0 = -10(4) + b; multiply 0 = -40 + b; add 40 to each side 0 + 40 = -40 + 40 + b; solve 40 = b (More)

(5,1) is a solution to the equation 2x-3y=7 is true.
2x-3y=2*5-3*1=10-3-7.

Slope of a Line that pass through the points (2,-1) and (6, 3) is 1.
let y=ax+b, -1=2a+b,3=6a+b, two equation add , -4=-4a,a=-4/-4=1.

Slope of a line pass through points of ( 3, 9) and (7, 15) is 3/2.
Slope= (15-9)/(7-3)=6/4=3/2.
