The slope-intercept form of linear equation , draw its graph and the of slope and y-intercept of line.
The slope-intercept form of given linear equation is , the slope of line is and the y-intercept of line is .
The linear equation is .
The slope-intercept form is .
The slope-intercept form of line is,
m is slope of line.
b is y-intercept of line.
Rewrite the given equation in x-term for y to get the equation,
Thus, the slope-intercept form is .
The given linear equation is .
The equation is linear so its graph is a line and there should be two pointsto draw a line.
Substitute 0 for y to get x-intercept,
Substitute 0 for x to get y-intercept,
Two points and are obtained from x- and y-intercepts and through these two points the graph of linear equation is shown in Figure (1).
Figure (1) shows the graph of line passes through points and .
The formula of slope-intercept form of line is,
The slope-intercept form of given linear equation from section1 is,
Compare the above equation with formula get the value of slope and the value of y-intercept .
Thus, the slope of line is and y-intercept of line is .
