Answer:
y = -2x+4
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
= (-4-2)/(4-1)
= -6/3
= -2
point slope form
y-y1 = m(x-x1)
y-2 = -2(x-1)
distribute
y-2 =-2x +2
add 2 to each side
y-2 +2 =-2x+2+2
y = -2x+4
in slope intercept form
y = -2x+4

Answer:</h2>

<h2>
Step-by-step explanation:</h2>
From the given graph, we can know two points:

Using the slope intercept form of the equation of a line, we get:

Where the slope is
and the y-intercept is 
From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:

And the slope intercept form of this equation is:

So the slope is
and the y-intercept is
, the systems formed by these two equations has no solution.
Answer:
x = 100
Step-by-step explanation:
365.12 x = 36512
36512 / 365.12 = x
x = 100

Answer:
(2, 1).
Step-by-step explanation:
x^2 - 4x + 5 = 0
(x - 2)^2 - 4 + 5 = 0
(x - 2)^2 + 1 = 0
The vertex is at (2, 1).
