Find the equation of the line perpendicular to y = - 2x + 3 that passes through the
point (4,9).

y=1/2x+7

Step-by-step explanation:

New slope is 1/2, so we need to plug in the coordinates to find b.

y=1/2x+b

9=1/2(4)+b

9=2+b

7=b

y=1/2x+7

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.
