Question

Write an equation in point-slope form for this line through point J(4,1) with slope -4. Can you show me step by step so i can do other problems just like this.... thanks

Answer 1

@agent0smith

Answer 2

use this \[\large y - y_1 = m(x-x_1)\]
plug in m = -4, and the point (4, 1) is your (x1, y1)

Answer 3

Once you do that, you're done.

Answer 9

Not really sure about 22, that's pretty hard to explain. You could draw two parallel lines of length AB, then make two perpendicular lines of length AB, and draw all four into a square.

For the next, find the slope through each pair of points, using \[\large m = \frac{ y_2 - y_1}{ x_2 -x_1 }\]

Once you get the two slopes, multiply them together. If it equals -1, they're perpendicular.

Answer 10

can you plug them in for me

Answer 11

for #23 mr @agent0smith

Answer 12

\[\large m = \frac{ -12 - (-10)}{ -5 -(-8) }\]and \[\large m = \frac{ -5 - (-6)}{ 17 -9 }\]
