Answer

Step-by-step explanation

The best way to graph the equation of a striaght line is to use the intercepts.

That is, the value of y when x = 0 and the value of x when y = 0.

y = -2x + 5

when x = 0,

y = -2x + 5

y = -2 (0) + 5

y = 0 + 5 = 5

First point on the graph is (0, 5)

when y = 0

y = -2x + 5

0 = -2x + 5

2x = 5

Divide both sides by 2

(2x/2) = (5/2)

x = 2.5

The second point is (2.5, 0)

So, to plot this graph, we just mark the two points obtained (0, 5) and (2.5, 0) and connect this two points.

The graph of this line is presented under 'Answer'.

Hope this Helps!!!
