The equation of line gh is y = 4x − 3. write an equation of a line perpendicular to line gh in slope-intercept form that contains point (2, 3).
y = 4x − 3
y = −4x − 5
11 over 4x − 3
y = negative 1 over 4x + 7 over 2

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.
