Slope Intercept Form

Y intercept To find the y-intercept, plug 0 in for x in the linear equation and solve for y. y=3x-6 (0, -6)

Y intercept The y-intercept is the point where a line crosses the y axis. At this point the value of x is 0.

Slope y=3x-6 To find the slope first find 2 points. (2, 0) and (0, -6) Then substitute in and solve

Slope Intercept Form y=mx + b m is the slope b is the y-intercept

Slope Intercept Form y=3x-6 The slope is The y intercept is

Slope Intercept Form To graph y=3x-6 Plot (0, -6) then count slope Up 3 right 1 Connect your points to make a line.

Writing an Equation Write the equation of the line with slope 3/8 and y-intercept 5. Use slope intercept form: y=mx+b Substitute in for m and b

You Try Write the equation of a line with slope -.5 and y-intercept -3

You Try Identify the slope and y intercept. y = -5x + 13 Slope:
