Slope Intercept Form
Slope-Intercept Form
When an equation is written in the form, y = mx + b, where m represents the slppe of the line, and b represents the y-intercept.
If you have two points and want to write the equation of a line, you need to
find the slope (m) and then use the equation y=mx+b and substitute the m and the (x,y) in and find b.
To write the equation of a line, you need to find
slope (m) and y-intercept (b)
The m in the y=mx+b is the
slope of the line (rise over run)
Write the equation if b = 3 and m = -2
y= -2x+3
Slope-intercept form for equation of a line.
y=mx+b
Write the equation if b = -7 and m = 1/2
y = 1/2x - 7
The b in y=mx+b is the
y-intercept (where the line crosses the y-axis)
Slope
The measurement of the change in the y direction(vertical change), over the change in the x direction(horizontal change), Slope is written as a fraction.
Y-Intercept
The point where the equation of a line crosses the Y-axis.
