Answer:
y - (-7) = 7(x - 4)
Step-by-step explanation:
The given points are (4. -7) and (5, 0).
The point-slope equation of a line is
y - y1 = m(x - x1),
where (x1, y1) is a point on the line, and m is the slope.
m = (y2 - y1)/(x2 - x1) = (-7 - 0)/(4 - 5) = -7/(-1) = 7
You can use either point for (x1, y1). I will use point (4, -7).
y - (-7) = 7(x - 4)
Answer:
f(2)=-2
Step-by-step explanation:
Find you x value and then look for where y is
So that means you go to horizontal line for 2, and then look where it lines up with the vertical line (-2)
Answer:
using Pythagoras theorem we have
Step-by-step explanation:
step 1 : draw the diagram based on the question.
you draw a line upward 13km and draw another one to the right 24km then draw another one down 6km, now you join the the last line to the original starting point.
Step 2: after drawing the diagram above you should draw a doted line from the end of the last line due south to bisect the first line due north and label the line 24km also since it forms a rectangle.
step 3: it now forms a right-angled triangle at the bottom then you apply the Pythagoras theorem
