A line with a slope of -2/5 that passes through the point (-10,8)

slamgirl [31]

Step-by-step explanation:

$m = - \frac{2}{3} \\ ( - 10 ,\: 8) = (x_1,y_1)$

$y-y_1=m(x-x_1)$

Plug in the values into the equation

$y - 8 = - \frac{2}{3} (x - ( - 10)) \\ y - 8 = - \frac{2}{3}( x + 10) \\$

$y - 8 = - \frac{2}{3} x - \frac{20}{ 3 } \\ y = - \frac{2}{3} x - \frac{20}{3} + 8 \\$

$y = - \frac{2}{3} x + \frac{4}{3}$

To solve for x-intercept , Arrange the values in

$ax + by + c = 0$

$- \frac{2}{3} x - y + \frac{4}{3} = 0$

To find x-intercept .let y = 0 in the above equation

$- \frac{2}{3} x - y + \frac{4}{3} = 0 \\ - \frac{2}{3} x - 0 + \frac{4}{3} = 0 \\$

$- \frac{2}{3} x + \frac{4}{3} = 0 \\ - \frac{2}{3} x = - \frac{4}{3}$

Solve for x ;

$x = 2$

To find y intercept , let x = 0

and solve for y .

I hope it helps <3

LenKa [72]

[67.9 %, 82.1 %] is the answer when it has 95% confidence interval for the proportion of test-takers who answered the question correctly. So the 95% confidence interval for the proportion of test takers is [67.9 %, 82.1 %] who answered the question correctly, In order to random sample of 144 test-takers and 75% answered question correctly. So the answer in this question is [67.9 %, 82.1 %].
