8. $y=-\frac{7}{3}(x-1)+5$

9. $y=\frac{4}{7}(x-2)-1$

10. $y=-\frac{3}{4}x+3$

Step-by-step explanation:

The equation of a line passing through points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is given as:

$y-y_{1}=(\frac{y_{2}-y_{1}}{x_{2}-x_{1}})(x-x_{1})$

For #8:

$(x_{1},y_{1})$ is (1,5) and $(x_{2},y_{2})$ is (4, -2) .

Now, plug in these values and find the equation of the line. This gives,

$y-5=(\frac{-2-5}{4-1})(x-1)\\y-5=(\frac{-7}{3})(x-1)\\y=-\frac{7}{3}(x-1)+5$

Therefore, the equation of a line passing through (1,5) and (4, -2) is $y=-\frac{7}{3}(x-1)+5$ .

For #9:

$(x_{1},y_{1})$ is (2,-1) and $(x_{2},y_{2})$ is (-5, -5) .

Now, plug in these values and find the equation of the line. This gives,

$y-(-1)=(\frac{-5-(-1)}{-5-2})(x-2)\\y+1=\frac{-5+1}{-7}(x-2)\\y+1=(\frac{-4}{-7})(x-2)\\y=\frac{4}{7}(x-2)-1$

Therefore, the equation of a line passing through (2,-1) and (-5, -5) is $y=\frac{4}{7}(x-2)-1$ .

For #10:

$(x_{1},y_{1})$ is (0,3) and $(x_{2},y_{2})$ is (4, 0) .

Now, plug in these values and find the equation of the line. This gives,

$y-3=(\frac{0-3}{4-0})(x-0)\\y-3=(\frac{-3}{4})(x)\\y=-\frac{3}{4}x+3$

Therefore, the equation of a line passing through (0,3) and (4, 0) is $y=-\frac{3}{4}x+3$ .
