Explanation Given: The y -intercept is 4. The equation of the line x + 5 y = 7 . Formula used: Slope-intercept form “ If a line has slope m and y -intercept b , then an equation of the line is y = m x + c .” Recall: (1) The equation of the line in slope-intercept form is y = m x + b , where m is slope of the line and b is y -intercept of the line. (2) “Two lines are perpendicular if and only if the product of their slopes is −1, or if one is vertical and the other horizontal.” Calculation: Obtain the slope the line x + 5 y = 7 by rewriting the equation in slope-intercept form. x + 5 y − x = 7 − x ( Subtract x from both sides ) 5 y = 7 − x 5 y ( 1 5 ) = 7 ( 1 5 ) − x ( 1 5 ) ( Divide both sides by 5 ) y = − 1 5 x + 7 5 By Recall (1), the slope of the above equation is − 1 5 (coefficient of x )

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…
