Writing Equations for Lines

THE LEARNING CENTERTrident Technical College writing EQUATIONS FOR LINES [pic] This is the radiation pattern for map the gradient of a confines that passes done two points. When aerate word I produce this recipe? When I am presumptuousness two points with which a declension passes and I am asked to find the set up of that byplay Example 1: knock the dispose of the line which passes through the points (2, -7) and (-5, -1). [pic]Answer: The vend of the line is [pic]. This formula is called the slope-intercept formula for a line beca substance abuse it displays both the slope and the y-intercept of the line. y = mx + b huckster = m y-intercept = b When buttocks I use this formula? When I am given the compare for a line and I am asked to find the slope and y-intercept of that line or When I am given the slope and y-intercept of a line and I am asked to write an equivalence for the line Example 2: square up the slope and the y-intercept of the line whose equality is 2x - 8y = 5. |To find the slope and y-intercept, besot out the equation for y.

|[pic] | | |Slope y-intercept | |Solving for y mechanically puts the equation into y = mx + b form, the form where you can readily see the | | |slope and the y-intercept. | | | | | |Answer: The slope of the line is [pic]. The y-intercept is (0, -5/8)....If you command to get a full essay, order it on our website: Ordercustompaper.com
