The younger brother will be 48 when Adam is 50
Answer:
1/8
Step-by-step explanation:
The slope of a line given two points is found by
m = (y2-y1)/ (x2-x1)
= (-2 - -3)/(4 - -4)
= (-2 +3)/(4+4)
1/8
A line is perpendiculat to another which has a slope of m if the perpendicular line has a slope of -1/m.
That means that if the product of slopes of two lines is -1, the two lines are perpendicular.
Here, y1=-7/4x, or m=-7/4
The perpendicular should have a slope of -1/m=-1/(-7/4)=4/7
Infinite, multiply it by any number divided by itself.
Ex. 1/2*2/2= 2/4
1/2*4/4=4/8 etc.
