It's
y = mx + b
where m is the slope of the line and b is the y intercept.

The general formula is y = mx +c where m is the slope c is constant and x y is point on the straight line
the value of m and c an be calulated from 2 points on straight line

There are several forms of the formula for a straight line. The most common are standard form, slope-intercept form and point-slope form.
Standard Form: ax+by=c
Here, a,b and c are constant with x and y variables.
Slope-Intercept Form: y=mx+b
This is probably the most common form. again x and y are variables, with m the slope of the line and b the y intercept (the place were the line crosses the y axis).
Point-Slope Form: y-y_1 = m(x-x_1)
In this form the line passes through the points (x_1, y_1) has slope m. Again, x and y are our variables.
In all of these forms, x and y depend on each other meaning that if you are given one, you can find the other.

The general formula is ax + by + c = 0,
u must understand the basic behind makingb the equation of a st. line which is " locus of a point having ratio of vertical to horizontal always remains same"

y = mx +c
x is the independant variable, y is the dependant variable , m is the slope or the tangent and c is the inetrecept.

y=mx+c
if positive or negative value whic varies on line direction

up or down?? left or right?? or on a slope??
there are many different "forms", slope-intercept, point-slope, etc etc...
