In this packet, we will learn how to write linear equations in slope-intercept form, and learn how to solve real life problems referring to this topic.
This packet contains an introduction text section, a PowerPoint presentation explaining the lesson, and another PowerPoint containing some practice problems.
Y= this stands for the y coordinate. Ex:(0,5)
X= This stands for the x coordinate. Ex: (4,0)
M= this stands for the slope of the line. Ex: in y=2x+4 the slope is 2
b= this stands for the y-intercept of the line Ex: in 2x+4 the y-intercept would be 4
This is slope-intercept form!
What I call the double point- slope equation:
y2-y1 / x2-x1
This helps find the slope when the problem gives us two points.
This presentation gives a short lesson on how to write linear equations in slope-intercept form.
