Question

really need help! medals will be given!!
Select the equation of the line that passes through the point (3, -1) and is perpendicular to the line on the graph.

y = -1
y = 3
x = -1
x = 3

Answer 1

where is the pic?

perpendicular lines have negative reciprocal slopes

Answer 2

whats the line on the graph ?

Answer 3

Its at (0,2.5)

Answer 4

no slope

Answer 5

so its a horizontal line ?

Answer 6

yes

Answer 7

a horizontal line is represented by y = a number.....but your looking for a perpendicular line....so that would be a vertical line and that is represented by x = a number. Now look at your points (3,-1)......so what does x = ??
HOY -- horizontal line, 0 slope, y = a number
VUX -- vertical line, undefined slope, x = a number
