The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...

The straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\), the gradient of the line, by forming a right-angled triangle using the ...

y = -2 - .5x + 2.5 y = .5 - .5x 4. Find the equation of the line which passes through the points ( 3, -2) and (1, 5). In this case two sets of coordinates are known but the slope is not known. This ...

In this case both the slope and the y intercept are known and the equation can be written ... This case involves the use of the two-point formula. Since the slope of a linear function is the same at ...

You express a point slope form equation as y – y 1 = m (x – x 1), where m represents the slope of the line, and (x 1, y 1) are the coordinates of the given point through which the line passes.
