A line passes through A(3,7) and B(-4,9) find the value of a if C (a 1) is on the line

Xelga [282]

What we need to do first, is to write the equation of the line through points A and B.

the slope of the line through A(3, 7) and B(-4, 9) is

$m= \frac{9-7}{-4-3}= \frac{2}{-7}=- \frac{2}{7}$

the equation of the line is :

$y-7=- \frac{2}{7}(x-3)\\\\y-7=- \frac{2}{7}x+ \frac{6}{7}\\\\y= - \frac{2}{7}x+ \frac{6}{7}+ \frac{49}{7}\\\\y= - \frac{2}{7}x+ \frac{55}{7}$

C(a, 1) is on this line so it must satisfy the equation:

$y= - \frac{2}{7}x+ \frac{55}{7} \\\\1= - \frac{2}{7}a+ \frac{55}{7}\\\\ \frac{2}{7}a= \frac{48}{7}\\\\2a=48\\\\a=24$

Zinaida [17]

9514 1404 393

Answer:

14.4 or 15 bags

Step-by-step explanation:

The number of yards covered by x bags is ...

(3 1/2)x = 50 1/4

x = (50 1/4)/(3 1/2) = 50.25/3.5 ≈ 14.4*

We assume that bags of chips are available only in integer quantities.

The PTA will need 15 bags of wood chips to cover the wet section.

_____

* The exact answer is 14 5/14. We hope that an integer number is the desired solution, as anything more precise than that seems inappropriate in this context.
