Is the line y=3x-7 parallel or perpendicular to 3x+9y=
9?Explain your answer

yes, perpendicular

Step-by-step explanation:

perpendicular lines on a graph has opposite reciprocal slope

3x+9y=9 ( put the equation in the  slope intercept form y=mx+b

9y=-3x+9

y=-3x/9+9

the slope of the first question is 3

the slope of the second equation is -1/3 x

yes the two lines are perpendicular

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
