Answer:
3/4
Step-by-step explanation:
Choose two coordinates on the line and use the slope formula to figure out the slope.
For example, use coordinates (0,-1) and (4,2).
Slope formula: y2-y1/x2-x1
2--1/4-0 = 3/4
Answer:
19km
Step-by-step explanation:
190km divided by 10hr = 19km per 1hr
So k=katie's' age
m=mara's age
k is 2 times as old as m
k=2m
sum is 24
add means sum
k+m=24
so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16
katie=16
mara=8
Ok then um so ya ok thx for the points though
