Question

Ex-23. Construct three different programs (IPO diagram, pseudocode, flowchart) to compute the equation of a line expressed as y-mx+b, given (A) the coordinates of two points (x,y), (X2,Y2); where m is the slope and b the y intercept. (B) the coordinates of one point(x), and b (the y-intercept) (C) The slope "m" and the y-intercept, "b."

Answer 1

ANSWER (A)

IPO DIAGRAM



PSEUDOCODE

PROCESS INPUT OUTPUT m (y2 -y1)/(x2 -x1) by1 m*(O - x1) x1, y1, x2, y2

1. START
2. Input x1, y1, x2 and y2
3. m = (y2 - y1)/(x2 - x1)
4. b = y1 + m*(0 - x1)
5. y = m*x + b
6. Output y
7. END

FLOWCHART


START Input x1, y1, x2, y2 m (y2 -y1)/(x2 - x1) Output y END


ANSWER (B)

IPO DIAGRAM
INPUT PROCESS OUTPUT x1, y1, and b

PSEUDOCODE

1. START
2. Input x1, y1 and b
3. m = (y1 - b)/x1
4. y = m*x + b
5. Output y
6. END

FLOWCHART

START Input x1, y1, and b Output y END

ANSWER (C)
