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)

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 -2/3, y-intercept (0, 1/3) User: 2x – y = 12
Weegy: This is an easy mathematical problem. In order to find the slope and the Y intercept of the equation all you need to do is bring the equation in the general form, y = mx + c. It will become y = 2x - 5. [ [ In this case as we can see 2 is the slope and -5 is the y intercept. ] ] User: (8, 0), m = - 3 Weegy: ((3 / 5) * 0.6) - ((2 / 3) * 0.15) = 0.26 Thanks for asking Weegy. User: Parallel to 3x – y =7 and passes through (- 1, 0) Weegy: (3x-2) squared is 9x^2 - 12x + 4. User: 5x - 6y =19 6x + 8y = -5 (More)
