First get slope
(4,-1) and (-2,3)
slope is
diff in y 4
---------- = ---- = -2/3
diff in x -6
use a point (-2, 3) and y - y1=M(x - x1)
y - 3= -2/3(x + 2)
y - 3= -2/3x - 4/3
+ 3 +3
y = -2/3x - 4/3 + 9/3 (3 is 9/3)
y = -2/3x + 5/3
A) x + y = 17
B) x - y = 27
Adding both equations:2x = 44
x = 22
y = -5
3⁽ˣ+ ₂⁾ =10 . TO SOLVE USE LOG NEERIAN ln (which base =e)
e⁽ˣ⁺²⁾lⁿ⁽³⁾ =e¹⁰ [the exponent on the 1st e is (x+2)ln(3)]
(x+2)ln3=ln10
xln3 + 2ln3 = ln10
x.ln3 = ln10-2ln3 and x =(ln10-2ln3)/ln3 =(2.302585-2.097224)/1.098612
x= 0.095903
Check the picture below
if it's a negative value, thus a negative rate, thus is decreasing, if it is a positive value, then increasing.
