Question

Please help (:
1. Which is the equation of the given line in slope-intercept form?
a. y=3x+2
b. y=3x-2
c. y=-3x+2
d. y=-1/3x+2

(THE LINE IS (-1,5 & 1,-1)

2. Which is the equation of the given line in standard form?
A. y = 2
B. y = 2x
C. x = 2
D. x = –2

(THE LINE IS 2,4 & 2,1)

Answer 1

wheres the line?

Answer 2

slope intercept form is --> y=mx+b
'M' is the slope or \[\frac{ rise }{ run }\]
'B' is the y-intercept

Answer 3

lets do this together.....first you need to find the slope using the slope formula :
slope(m) = (y2 - y1) / (x2 - x1)
(-1,5) x1 = -1 and y1 = 5
(1,-1) x2 = 1 and y2 = -1
now we sub
slope(m) = (-1 -5) / (1 - (-1)
can you take it from here and find the slope ?

Answer 4

yes thank you very much! :)

Answer 5

that is just the slope...that is not the equation in slope intercept form

Answer 6

do you still need help ?
