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)
Slope
• y=3x-6 • (2, 0) and (0, -6)
