You can put this solution on YOUR website! 20x + 5y = 3
to get the gradient, solve for y and put the equation into slope intercept form.
start with:
20x + 5y = 3
subtract 20x from both sides of the equation to get:
5y = -20x + 3
divide both sides of the equation by 5 to get:
y = -20/5 * x + 3/5
this simplifies to y = -4 + 3/5.
the equation is now in slope intercept form of y = mx + b
m is the slope
b is the y-intercept.
the slope is equal to -4 which is the gradient you are looking for.
