- 3. Slope given points
- 4. y = mx + b
The most common form for a linear equation is called
slope-intercept form.
- 5. y = mx + b
The most common form for a linear equation is called
slope-intercept form.
The equation for this form is y = mx + b.
- 6. y = mx + b
x represents the input.
- 7. y = mx + b
x represents the input.
y represents the output.
- 8. y = mx + b
x represents the input.
y represents the output.
m is the slope of the line.
- 9. y = mx + b
x represents the input.
y represents the output.
m is the slope of the line.
b is the y-intercept.
- 10. To graph:
Plot the y-intercept first.
- 11. To graph:
Plot the y-intercept first.
From that point, use the slope to rise and run to the next
point.
- 12. To graph:
Plot the y-intercept first.
From that point, use the slope to rise and run to the next
point.
Connect with a line.
