Question

What's the equation of stright line ?

Answer 1

y = mx + c.

Answer 2

The eqn. of a straight line is:-

ax+by+c=0

where a,b,c are constants.

Answer 3

y = mx + b

Answer 4

y = a + bx

where (x,y) is a point in the line, when you find the points in x and y using the equation you will get a line. These points can be ploted on a graph to get a straight line.

Answer 5

y = ax + b       , where

a - is the slope coefficientt, and

b - is the point where the line passes the y axis

Answer 6

any linear equation in one degree rep. a straigt line

Answer 7

y=mx+c

Answer 10

y=mx+c

Answer 11

Specifying the slope and the "y intercept", b, of the line.

Specifying the slope of the line and one point on the line.

Specifying two points through which the line passes.

(Comment: Since the "y intercept" is simply the point (0,b), the first and second entries above are closely related.)

From the above information, in any of its forms, we can determine the equation of a straight line.

Given the slope m and "y intercept" b, the equation of the line is

y = m x + b

Given the slope of the line m and one point P1 = (x1,y1) through which the line passes, we can formulate the equation as as:

(y- y1)/(x-x1)= m

We have written this equation in a form which makes it clear that the slope calculated between any point (x,y) on the line and the given point P1 is the same. However, the relationship generally gets simplified algebraically to:

y = m (x-x1)+ y1

This form is tidier, but conceals the simple truth behind how the equation was crafted, namely as a statement about the slope of the line.

Given that the line passes through the two points P1 = (x1,y1) and P2 = (x2,y2), we first find that the slope of the line is

slope: m = (y2- y1)/ (x2-x1)

We can then use the form shown in the second example above---namely,

y = m x + b

Answer 12

ax + by + c =0

Answer 13

y =ax + b.

Answer 14

y=mx+c

This is called the slope-intercept form because "m" is the slope and "c" gives the y-intercept.
