Question

i need help solving a system from the points (0,4) and (1,3)

Answer 1

do you know how to find the slope

Answer 2

use www.mathways.com
that's helps alot

Answer 3

what are your x and y's

Answer 4

Xs are always first
ys are second
not mater what it is allways like that (X,Y)

Answer 5

then count up how many spaces and over how many spaces to the next point.
for the points (-3,4) and (2,-1) the slope would be 1/1

Answer 6

very good

Answer 7

what is the y intercept it is lie (0,___) the blank is a y intercept

Answer 8

are you trying to find the slope given points (0,4) and (1,3) ??

Answer 9

because it is not 1/1

Answer 10

oops. looks Like I need help too.

Answer 11

slope(m) = (y2 - y1) / (x2 - x1)
(0,4)...x1 = 0 and y1 = 4
(1,3)...x2 = 1 and y2 = 3
now sub
slope(m) = (3 - 4) / (1 - 0)
slope(m) = -1/1

Answer 12

i was so close

Answer 13

now what exactly do you need to do for this question ? Do you need to come up with the line that these points are on ?

Answer 14

or do you just need to find x and y intercepts ?

Answer 15

no, i need tofind the y intercept and then the x, and lastly i need to use subsitution to find where the lines intersect.

Answer 16

we need the equation
use y = mx + b
we already know slope(m) = -1...so we need to find y intercept (b)
use either of your points (1,3)..x = 1 and y = 3
now sub
y = mx + b
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so your equation of your line is : y = -1x + 4

are you still with me ?

Answer 17

are you needing to find the line for (-3,4) and (2,-1) ??
