The graph of the line - 2 · x + 5 · y = 10 is shown in the image attached below.
How to graph a line on Cartesian plane
Herein we must graph a line in implicit form, that is, line is of the form:
a · x + b · y = c
Where:
- a, b, c - Real constants.
- x, y - Variables.
According to geometry, any line can be constructed by knowing two distinct points on Cartesian plane. The procedure is now summarized:
- Equalize x to 0 and clear y.
- Equalize y to and clear x.
- Mark the points on Cartesian plane.
- Draw the line that passes through the two points.
Step 1:
- 2 · 0 + 5 · y = 10
y = 2
P₁(x, y) = (0, 2)
Step 2:
- 2 · x + 5 · 0 = 10
x = - 5
P₂(x, y) = (- 5, 0)
