Solution:
we have been asked to find
Which equation represents the graphed function?
As we can see in the graph, the line is passing through the point (2,0) and (0,-3).
As we know the equation of the passing through two points is given by the formula
So the equation of the line will be
A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add
to both sides</em>
<em>divide both sides by 2</em>
Answer:
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract
from both sides</em>
