Answer:
y = negative 2 (x minus one-half)
Step-by-step explanation:
The equation of a line is given as:
y = mx + c, where m is the slope and c is the intercept on the y axis.
The equation of a line going through (0, 1) and (1, - 1) is calculated using:
The solution of two lines is at their point of intersection. The equation of the line that would not have any solution with y = -2x + 1 would be a line that is parallel to y = -2x + 1. Since the two lines would be parallel to each other, their would be no intersection and therefore no solution.
Two lines are said to be parallel to each other if they have the same slope. The slope of y = -2x + 1 is gotten by comparing with y = mx + c, therefore the slope m = -2. From the options the only line with a slope m = -2 is y = -2(x -1/2). Therefore y = -2(x -1/2) is parallel to y = -2x + 1 and would have no solution
I will show you how to solve by elimination. You have two equations. The goal of this method is to cancel out one of the variables.
3y=x-1
x-2y=2 ----> 2=x-2y (just flipping it around visually)
If we align the two equation and subtract them...
3y=x-1
-(2=x-2y) "x is canceled out"
---------------
3y-2=-1+2y "one variable equation now"
y=1
Plug in 1 for y into any equation to get corresponding x value.
3y=x-1
3(1)=x-1
x=4

Hey!
-----------------------------------------------
Solution:
4(9x + 7) = x - 4
36x + 28 = x - 4
36x + 28 + 28 = x - 4 + 28
36x = x + (-32)
36x - x = x - (-24) - x
35x = -32
35x/35 = -32/35
x = -32/35
-----------------------------------------------
Answer:
x = -32/35
-----------------------------------------------
Hope This Helped! Good Luck!
