Answer:
y = -4x + 14
Step-by-step explanation:
using the slope intercept form of a line
y = mx + c
Given points
slope (m) =
[tex] = \frac{y2 - y1}{x2 - x1} \\ = \frac{2 - 10}{3 - 1} \\ = \frac{ - 8}{2} \\ = - 4[/tex]
taking one point as for filling x and y and finding the y intercept (c)
y =mx + c
10 = (-4) × 1 + c
10 + 4 = c
14 = c
therefore the equation is
y = -4x + 14
Answer:
2y + 8x = 28
Step-by-step explanation:
Hi there
So we are going to solve this together
m = y - y1/y2- y1 =x - x1/x2 - x1
y - 10/ 2- 10 =x - 1/ 3 -1
y -10/-8 =x - 1/2
cross multiply
2(y - 10) =-8(x -1)
2y - 20= -8x + 8
Collect terms
2y +8x = 8 +20
ANSWER = 2y + 8x = 28
Hope this helps you!
Bye , have a nice day :-)
