point 1 = ( -1 , 5 ) point 2 = ( 5 , -5 )
equation of a line: y = mx + b
Find Slope (m):
( 5 - (-5)) / (-1 - 5))
= 10 / -6
= -3 / 2
slope = -3/2
Find y-intercept (b):
y = mx + b
y = -3/2 * x + b
5 = -3/2 * -1 + b <-------------- use the x and y coordinate of one of the . points. I used point 1 ( -1 , 5 )
b = 7/2 or 3.5
Assemble:
y = -3/2 * x + 3.5
I’m pretty sure it’s
Y=3x-3

Answer:
The equations are not compatible
Step-by-step explanation:
y = -4x + 3
8x + 2y = 8
substitute for y:
8x + 2(-4x + 3) = 8
simplify:
8x - 8x + 6 = 8
6 ≠ 8
