Question

which of the following is an equation of the line A graphed in the xy plane that passes through the point (-1, 3.5) and is perpendicular to line B whose equation is x + 4.5=0

Answer 1

Hello there,

which of the following is an equation of the line A graphed in the xy plane that passes through the point (-1, 3.5) and is perpendicular to line B whose equation is x + 4.5=0

Answer: y=3.5

Answer 2

y=3.5

Explanation:

To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.

x+4.5=0

x=-4.5

The slope is 0. To create a perpendicular line, it must y= a value which will cross (-1. 3.5).

y=3.5
