Answer:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept
Step-by-step explanation:
slope-intercept equation for graph a: y = -x + 1
standard-form equation for graph a: x + y = 1
:::::
Slope of line through (0,-2) and (3,4) = (4-(-2))/(3-0) = 2
Slope-intercept equation for graph b: y = 2x-2
Standard form: 2x-y = 2
This equation is incorrect. The equation simplifies to -3=4 which is incorrect.
3(-3)=-9. 3(2)=6
-9+6=-3
-3=4 FALSE
x=-1, y=5. (-1, 5). The first number is -1 and the second number is 5.
6x+2y=4
2x+4y=18
---------------
-2(6x+2y)=-2(4)
-------------------------
-12x-4y=-8
----------------
-10x=10
x=10/-10
x=-1
6(-1)+2y=4
-6+2y=4
2y=4-(-6)
2y=4+6
2y=10
y=10/2
y=5
