We can solve it algebraically:
(subtract 4 from both sides to isolate
(square both sides to get rid of square root on left side
(divide both sides by 3 to isolate y)
2 points on the line are (10,5) and (2,-3)
slope between is 1
point slope is. y-5=(x-10) or y = x-5
Answer:
b = 3/4
Step-by-step explanation:
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → <em>3/4</em>
That would be 2/12, or 1/6 of a chance. As a percent, that would be roughly 16%.
