What are the points?
OpenStudy (anonymous):
can you type them out
OpenStudy (anonymous):
(-2,5) (9,-4)
OpenStudy (anonymous):
The first point (-2, 5):
x1 = -2
y1 = 5
The second point (9, -4):
x2 = 9
y2 = -4

y2 - y1
Slope=--------
x2 - x1
OpenStudy (anonymous):
Can you do it from here?
OpenStudy (anonymous):
i suck at this
OpenStudy (anonymous):
ok fine!
-4 - 5 -9
slope=--------- = -----------
9 + 2 11
OpenStudy (anonymous):
-9 / 11 is the answer?

Write the equation in standard form of the line through J(4, 1)with slope –4
OpenStudy (anonymous):
Use the point slope form
y - y1 = m(x - x1)
OpenStudy (anonymous):
come on :(
OpenStudy (anonymous):
kkkkkkkkkkk!!!

OpenStudy (anonymous):
x1 = 4
y1 = 1
m = slope = -4
OpenStudy (anonymous):
I said okay okay...............
OpenStudy (anonymous):
so thats the answer?
OpenStudy (anonymous):
y - y1 = m(x - x1)
y - 1 = -4(x - 4)
y - 1 = -4x + 16
y - 1 + 1 = -4x + 16 + 1
y = -4x + 17 <----- Answer
OpenStudy (anonymous):
thank you !!!

A. 4x – 2 = 3x + 6 B. 4x – 2 + 3x + 6 = 180
x = 8 7x + 4 = 180
x = 25.1
