Write the equation for this line in slope-intercept form.

If the y-intercept was +3 and the slope was 4, which equation is in the correct slope intercept form, y=mx+b.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

Write the equation for this line in slope-intercept form.

slope =​ (a)   y-intercept​ (b)

• no

• yes

Remember equations are written as y=mx+b. Create the equation by finding the slope from rise/run and the y-intercept by looking at where it crosses the y-axis. You can also create an equation by making a List & Spreadsheet, Data & Statistics, Menu 4, 6, 1.
