Answer
Explanation
To plot a graph, given the equation of the straight line, we simply obtain the intercepts (x and y intercepts) and connect those to plot.
x-intercept
This is the point where the graph crosses the x-axis and it is the value of x when y = 0.
y = -½x + 2
when y = 0
0 = -½x + 2
Multiply through by 2
0 = -x + 4
x = 4
So, first point, (4, 0)
y-intercept
This is where the graph crosses the y-axis and it is the value of y when x = 0
y = -½x + 2
when x = 0
y = -½(0) + 2
y = 0 + 2
y = 2
So, the second point, (0, 2)
So, this graph is plotted and presented under 'Answer'
