3x+y=19

y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:

19-3x=x+3

19-4x=3

-4x=-16

x=4, and since y=x+3

y=7  so the solution is the point:

What is the slope of all lines perpendicular to the line y=(2/3)x+7
Alexandra [31]

Answer:

The slope is -3/2

Step-by-step explanation:

<u>A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal. </u>

Example:  Find the line perpendicular to y = 3x

First, you flip the sign which makes 3 into -3

Next, you make the reciprocal which makes -3 into <u>-1/3 </u>

Problem:  Find the line perpendicular to y = (2/3)x + 7

First, you flip the sign which makes 2/3 into -2/3

Next, you make the reciprocal which makes -2/3 into <u>-3/2</u>

Answer:  The slope is -3/2
