4x+5y = 20
5y = -4x+20
y = -4/5x+4
So the slope is -4/5 or as -0.8 and the y intercept is 4
The slope is the gradient which is y2-y1/x2-x1 To find the y int you set the equation of the line equal to zero i think :/
An equation of a line requires two parameters. The slope, by itself, is not enough.

But it's not an equation because there is no equal sign and no points are given.
It equals to the equation of a straight line.

In order to find the equation of a tangent line you must take the derivative of the original equation and then find the points that it passes through.
If you mean: y = 2x-4 then it is equal to a straight line equation

An equation has an equal sign, which means that we know what the variable is equal to :)

By finding the line of best fit and using the straight line equation formula.
But it's not an equation because there is no equal sign and no points are given.
The equation for the line is y = mx +b the slope is the value of m For example if y = 3x +4 the that is the equation that completely defines the line; its slope is 3
It equals to the equation of a straight line.
Assuming you want the equation of the straight line between the two points (x0, y0) and (x1, y1), the equation is: y - y0 = m(x - x0) where m is the gradient between the two points: m = (y1 - y0) ÷ (x1 - x0) Note: if the two x coordinates are equal, that is x0 = x1, then the equation of the line is x = x0.
Subtract the equation of one line from the equation of the other
