To find the slope from two points, use the equation m = (y2-y1)/(x2-x1)

substitute
m = 4-2/5-0 = 2/5
the slope is 2/5

the line intercepts the y axis at (0,2), so the y intercept (b) is 2

slope intercept form: y = mx + b

so the slope intercept equation for the line is:
y = 2/5x + 2

In the xy -coordinate plane, the coordinates of point s are (-2,-6), and coordinates of point T are (18,9). Point Q lies on line

ira [324]

Answer:

(6,0)

Step-by-step explanation:

The coordinates of the points dividing the line segment in ratio m:n can be calculated as:

$(\frac{mx_{2}+nx_{1}}{m+n} ,\frac{my_{2}+ny_{1}}{m+n} )$

Here x1, y1 are the coordinates of first point S (-2, -6) and x2, y2 are the coordinates of second point T(18, 9).

In this case m will be 2 and n will be 3 as the ratio is 2:3

Using all these values we can find the coordinates of point Q

$( \frac{2(18)+3(-2)}{2+3},\frac{2(9)+3(-6)}{2+3} )\\\\ = (\frac{30}{5} ,\frac{0}{5} )\\\\ =(6,0)$

Thus, the coordinates of point Q which divides the line segment ST in ratio of 2:3 are (6,0)

In ΔRST, m < R = 104°, r = 20, and t = 10. Find the m < S, to nearest degree.

Answer:

47°

Step-by-step explanation:

The law of sines helps you find angle T. From there, you can find angle S.

sin(T)/t = sin(R)/r

sin(T) = (t/r)sin(R) = (10/20)sin(104°)

T = arcsin(sin(104°)/2) ≈ 29°

Then angle S is ...

S = 180° -R -T = 180° -104° -29°

∠S = 47°
