2. Find the equation of the line shown. The equation will be x=−3
3. Graph the linear equation using the slope and y-intercept.
y−intercept =1
While slope= 2
5 : this shows that the slope of equation is positive. This indicates a change of x
by 5 units and the value of y change by 2 units from the y-intercept. This means the co ordinates of the
line will be (0,1) and (5,3).
