Answer:
B. y = -3/4x + 5/2
Step-by-step explanation:
Take two points from the graph, let's use (-2, 4) and (2, 1):
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (1 - 4) / (2 - (-2))
= -3/4
Find y-intercept using slope above and anyone point:
y = mx + b
(1) = -3/4(2) + b
1 = -3/2 + b
b = 1 + 3/2
b = 5/2
Equation of line using m and b above:
y = mx + b
y = -3/4x + 5/2
88 % students of the class hand in their projects on time
<em><u>Solution:</u></em>
Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time
Total number students = 25
Students hand in their projects on time = 22
<em><u>To find: percent of the class hand in their projects on time</u></em>
Substituting the values, we get
Thus 88 % students of the class hand in their projects on time
