,x and y intercepts
• x -intercepts crosses the x-axis
• y-intercepts crosses the y-axis
• the y-axis is also the line "x = 0“
• the x-axis is also the line "y = 0"
• The x-intercept of a line is the point at which the line
crosses the x axis. ( i.e. where the y value equals 0 )
x-intercept = ( x, 0 )
• The y-intercept of a line is the point at which the line
crosses the y axis. ( i.e. where the x value equals 0 )
y-intercept = ( 0, y )

,Gradients
• M=gradient
• How steep the line is.
WITH GRAPH
• For every one across to the right,

x1 5=k+1/4
• Y2-y1/x2-x1 m=10-1/5-2 20=k+1
m=9/3 19=k
m=3 k=19

, Equation of a straight line
• Y=mx+c is the equation of a straight line.
• M=gradient
• C=y-intercept
WITH GRAPH
• Find gradient and y-intercept .
WITHOUT GRAPH
• 1) Find gradient using y2-y1/x2-x1
• 2) Find y-intercept by substituting one of the coordinates
into the formula.
