Find an equation of the the line satisfying the given conditions. through (7, 2); perpendicular to 4x + 9y = 46 9x - 4y = 1 • 9x - 4y = 55 4x - y = 55 9x + 4y = 55

  9x - 4y = 55

Step-by-step explanation:

The equation for the perpendicular line can be written by swapping the x- and y-coefficients and negating one of them. Usually we choose to negate the one that makes the x-coefficient positive. Here, that process gives ...

  9x - 4y = <some constant>

The value of the constant can be found by putting the (x, y) values of the given point into the left-side expression:

  9x - 4y = 9·7 -4·2 = 55

  9x - 47 = 55

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
