The answer to this problem should be 1.25
Answer:
Draw all these points and draw a straight line through all of them.
Step-by-step explanation:
y = mx + b
x - 4y = 4
-x -x
-4y = -x + 4
/-4 /-4
y =
-1
(0,-1),(4,0),(-8,-3),(-4,-2),(8,1) - The first graph attached
3x+y=-1
y = -3x - 1
(0,-1),(-1,2),(-3,8),(2,-7),(3,-10) - The second/last graph attached.
Hope this helps!
The answer will be 5.
|5-4|=1
Answer:
13 miles
Step-by-step explanation:
It tells us that her house is 5 miles from the Post Office. So we know that each unit on the grid is 1 mile. Lucy walks from her house to the post office to the bank. The shortest path is the hypotenuse of the right triangle. We have one side length. Now, we count the post office to bank's length. It is 12 miles. The Pythagorean theroem is a^2+b^2=c^2 so 5^2+12^2=c^2 Solving this, we get c=13. The shortest path is 13 miles.
