MATH 10005 SLOPE AND FINDING THE EQUATION OF A LINE KSU Definitions: Slope: of a line tells how fast changes for each unit of change in . Linear equation in two variables: is an equation that can be written as + = where and are real numbers and and cannot both be zero. Important ...
The "point-slope" form of the equation of a straight line is:y − y1 = m(x − x1)The equation is useful when we know:one point on the line: (x1, y1) and the slope of the line: m,and want to find other points on the line.Have a play with it (move the point, try ...
