Answered by admin @
Identify any two coordinates on the graph:
⇒ (0, 1) and (4, 3)
Find the Slope :
Slope = (y2 - y1) / (x2 - x1)
Slope = ( 3 - 1) / (4 - 0) = 2/4 = 1/2
Find the y-intercept:
From the graph, the line cuts the y-axis at y = 1
⇒ y intercept = 1
Form the slope-intercept equation:
equation : y = mx + c
⇒ y = 1/2 x + 1
Answer: (d) y = 1/2 x + 1
