HELP! NEED HELP!
Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).
Write the equation of the line that is parallel to the line 4x − 3y = −12 and passes through the point (−3, 4).
Hint: The product of the gradients of perpendicular lines = -1
what are gradients?
The gradient of a line y=mx+c is m.
So first, identify the gradient of the line y = 2x + 2 which is....?
Please just answers for these two
2
Correct. So the gradient of the unknown line is....?
1/2?
or 2 again?
@mukushla PLease answer or dont stare at it for 20 mins. I need help not a stalker. :D
Sorry for late response @Brandon_Sirota. Server issues. You were close. The gradient of the unknown line is -1/2. Since 2*-1/2=-1. Now given the gradient -1/2, and a point (6,3) through which the line passes. I believe you can get the equation of the line. Use the same methodology for the second question, the only difference being that the gradients of parallel lines are equal. I hope that helps.
