The standard form of a linear equation is y = mx + b
where m is the slop of the line, and b is the y intercept.
If you have two points (x1,y1) and (x2,y2), you can get the slope with the following formula:
m = (y2-y1)/(x2-x1)
if you plug this number in to the equation you can then plug in any (x,y) point on the line to solve for b.

I suggest that the simplest way is as follows:Assume the equation is of the form y = ax2 + bx + c.Substitute the coordinates of the three points to obtain three equations in a, b and c.Solve these three equations to find the values of a, b and c.
y = 7x - 4

In a standard form equation of a linear equation, represented as (Ax + By = C), (C) is the constant term on the right side of the equation. To find (C), you can rearrange the equation by isolating it on one side. For example, if you have (Ax + By = k), then (C) is simply (k). If you're given points or other information, substitute those values into the equation to solve for (C).

A linear equation with an undefined slope is an equation where, when graphed, forms a vertical line. For example: when given 2 points: (2, 4) (2,7) ~ The x-values are the same, while the y-values differ, which would create a vertical line when the points are graphed
The set of points whose coordinates satisfy a given equation is called the graph of the equation. For example, in the case of a linear equation, the graph is a line, while for a quadratic equation, it is a parabola. This collection of points visually represents the relationship described by the equation in a coordinate system.
To write the equation of a linear function given two points, you can use the slope-intercept form, (y = mx + b). First, calculate the slope (m) using the formula (m = \frac{y_2 - y_1}{x_2 - x_1}). Then, substitute one of the points into the equation to solve for the y-intercept (b). Finally, write the complete equation using the calculated slope and y-intercept.

But it's not an equation because there is no equal sign and no points are given.
To identify the slope in a linear equation, rearrange the equation into the form y = mx + b. The term m is the slope.
There are several ways, depending on the form of linear equation you want. I prefer the slope-intercept form, y = mx + b. Given two points, (x1, y1) and (x2, y2), we can calculate the values of m and b. The slope is m = (y2 - y1)/(x2 - x1). Plugging this and the coordinates of one of the points (say, (x1, y1)), we getb = y1 - mx1.But you are probably more interested in the two point form (for obvious reasons). This is basically an equation of the slope at a general point (x, y) with that at (x2, y2), namely (y - y1)/(x - x1) = (y2 - y1)/(x2 - x1).
Without an equality sign the given expression is not an equation
