You can put this solution on YOUR website! Draw the graphs of the equation using the points where they cross the axis,i.e.where x =0 and y=0.for each graph,determine the gradient.y-3x=9.
===============
Good idea.
y - 3x = 9
To find the y-int, set x = 0
---> y = 9, the point (0,9)
============
To find the x-int, set y = 0
---> x = -3, the point (-3,0)
============================================
determine the gradient
The gradient is the slope, m.
y - 3x = 9
Solve for y
y = 3x + 9
The slope, m, is the coefficient of x
m = 3
