Question

Y = 5-3x, Darw the graph of the function. Use the find the value of y when x=4, and when x = 5​

Answer 1

The line passes through (4, -7) and (5, -10).

Explanation:

When x = 4, y = 5 - 3(4), or 5 - 12, or -7. Thus the point (4, -7) lies on the graph. Similarly y = 5 - 3(5) = -10 when x = 5. Thus, the line also goes through (5, -10). Plot these two points and draw a line through them. Doing this will result in the desired graph.
