On a sheet of graph paper, using a scale

of 1 cm to represent 1 unit on the x-axis
and 1 cm to represent 5 units on the
y-axis, draw the graph of y = 2x + 9 for

Answer:

The answer is below

Explanation:

A linear graph has an equation of the form:

y = mx + b,

where y and x are variables, m is the slope (rate of change) of the graph and b is the y intercept (value of y when x is 0).

Given a graph, with an equation y = 2x + 9, to plot, we have to first draw a table for the respective values of y for -8 < X < 4.​

x: -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4

y: -7 -5 -3 -1 1 3 5 7 9 11 13 15 17

The graph was plotted using geogebra online graphing calculator
