<span>The power of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number.</span>
Use the point-slope form of the equation of a straight line
y - y1 = m(x - x1) here m = (2/5), x1 = 2 and y1 = -1.
y -(-1) = (2/5)(x - 2)
y + 1 = (2/5) (x - 2)
multiplying through by 5:-
5y + 5 = 2x - 4
5y = 2x - 9

Answer:
z = 110°
Step-by-step explanation:
Angles z and the one marked 70° form an linear pair, hence are supplementary.
z = 180° -70° = 110°
<h3>Angles where chords cross</h3>
The angle made by two chords is half the sum of the arcs intercepted by those chords. Here, that means ...
70° = 1/2(60° +x) ⇒ x = 140° -60° = 80°
The arc w completes the circle of 360°, so we have ...
w +x +79° +60° = 360° ⇒ w = 360° -219° = 141°
Finally, z is the average of w and 79°:
z = (w +79°)/2 = (141° +79°)/2 = 110° . . . as above
