Answer:
p=11
Step-by-step explanation:
let A(3,7),B(-6,1),C(9,p) be the points.
or
B(-6,1),A(3,7),C(9,p) are the points in the same line.
let A divides BCin the ratio k:1
Write the equation of the line in either point-slope form or slope-intercept form.

Answer:
<u>y = -3x - 0.25</u>
Step-by-step explanation:
Write the equation of a line that has a slope of -3 and passes through the point (1.25, -4).
We'll use the point-slope form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
We are told the slope, m, is -3.
y = -3x + b
We need to find a value for b that will cause the line to go through point (1.25,-4), We can do that by entering this point in the equation we have this far:
y = -3x + b
-4 = -3(1.25) + b
-4 = -3.75 + b
-0.25 = b
<u>The equation is: y = -3x - 0.25</u>
