Which of these is a point slope equation of the line that is perpendicular to y-8=3(x-10) and passes through (-2,7)?

The point slope form is:  

Step-by-step explanation:

Recall the general point-slope form of a line of slope "m" and going through a point , is given by:  

Notice therefore, that the given line is expressed in "point-slope" form

where the slope is given by the value: "3".

Recall that the slope of a line perpendicular to another given line of known slope "m" is the "opposite of the reciprocal" of that "m". That is:

Then for our case, the line perpendicular to the one given, must have slope given by:

So now we can create easily the point-slope form of the requested perpendicular line that goes through the point (-2,7) using the general point-slope form mentioned above:

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

50-60=10
