Slope Intercept Form

Y intercept

• The y-intercept is the point where a line crosses the y axis.

• At this point the value of x is 0.

• To find the y-intercept, plug 0 in for x in the linear equation and solve for y.

• y=3x-6 (0, -6)

X intercept

• The x-intercept is the point where a line crosses the x axis.

• At this point the value of y is 0.

• To find the x-intercept, plug 0 in for y in the linear equation and solve for y.

• y=3x-6 (2, 0)
