Ax + By + C = 0where A, B, C are integers, is called the general form of the equation of a straight line.Problem 7. What number is the slope of each line, and what is its meaning?a) x + y − 5 = 0This line is in the general form. It is only when the line is in ...
Ax + By = C Given either of the linear equations above, you can convert to standard form by simply rearranging the equations to isolate the constantCon one half of the equation. If there are any fractions, then multiply both sides of the equation by the denominator of the fractions to rem...
B. y=x-2 C. y=2x-2 D. y=2x+4 E. y=2x+2 7. The table show some values of a linear function. Which linear function is defined by these values. A.y=12x−3 B.y=33x−1 C.y=x−4 D.y=2x−3 E.y=32x+2
-1. if the equations of the two lines are given by ax + by + c = 0 and a’ x + b’ y + c’ = 0, then they are perpendicular if, aa’+ bb’ = 0. (again, you can arrive at this result if you find the slopes of each line and equate their product to -1.) also, ...
It should be noted that there are only two unknowns in theequation of a straight linebecause the equation of every straight line can be put in the form ax + by + c = 0, where a and b are two unknowns. It is important to note here that x and y are not unknowns. In fact, th...
In Ax + By = C, what does everything stand for? Does the x mean the x-axis, y mean y-axis, and C mean slope? Context is Key: In mathematics, a lot of the struggle involved in understanding problems comes from understanding the context....
