A line that passes through the points (–4, 10) and (–1, 5) can be represented by the equation y = (x – 2). Which equations also
lyudmila [28]
The equation y=x-2 do not represents the line that passes through the two point, since for example -4-2=-6, not 10. So (-4,10) is not on the line. 
Let find the equation of the line:
First compute the slope using formula:
<span> </span>\frac{y_2-y_1}{x_2-x_1}= \frac{5-10}{-1-(-4)}= \frac{-5}{3}
So the equation is in the form:
y=\frac{-5}{3}x+s\text{ wherein s is another parameter. }
For x=-4 we get the equation:
10=\frac{-5}{3}(-4)+s
Solving the above equation for s we get:
s= \frac{10}{3}
The equation then is the following:
y=\frac{-5}{3}x+\frac{10}{3}

The correct answer then is equation 2 and equation 3.
