If the line through (x 5) and (4 3) is parallel to a line with slope 3 find x.


Sagot :

parallel means have the same slope
(y2-y1)/(x2-x1)=m
(4-x)[(3-5)/(4-x)=3]
3-5=3(4-x)
-2=12-3x
-14=-3x
x=14/3

Hope this helps

Sol'n:
Two points intercept form:
(y2-y1)=m(x2-x1)
at point (x,5) & (4,3)
where 'm' is the slope and it is equal to 3 because it is parallel.
Therefore;
(3-5)=3(4-x)  
X=4.67
