4x + 2y = 8 can be restated as 2y = -4x + 8 : y = -2x + 4 The equation is now in the standard form y = mx + c which is the equation of a straight line.
When establishing points to enable a straight line graph to be drawn, try to determine points that are a reasonable distance apart.
Start by taking x = 0 then y = 4
and when y = 0 then x = 2
As the two coordinates for x are closest to one another, choose the third point where x has a value of (say) -2 then y = 8.
The three points are thus (-2, 8) (0, 4) and (2, 0).
False
A scatter graph. A line graph need not involve minute changes.
The best way to make a graph is to draw straight axis lines with a ruler and space the points equally. Finally, plot the points. A cleaner, faster method, can be found by using a spreadsheet software, like excell.
Extrapolation.
it is a straight line equation with a slope of 1 and a y intercept of -4
With only two points you don't know the direction of the graph. Drawing a graph using only two points can result in the diagram being wrong.
The graph showed the results from his experiment. You can graph the data points to see what type of curve your equation defines.
A graph that displays data by using points joined together by line segments.
You could graph this Polynomial by using substution to solve for two points..which will define a line. If x=16, then y=0, If x=0, then y=8. Graph this line and you have the solution set for the equation.
if the linear equation is x+y=1 means we are having the graph points (1,0) (2,-1)....using this graph we can draw the graph
False
no
To calculate the potential difference from a graph, you need to determine the vertical distance between two points on the graph that correspond to different potential values. This vertical distance represents the potential difference between those two points. You can measure this distance using the scales on the axes of the graph.

you create ordered pairs or a serious of (x,y) points on the graph which you can plot and connect with a straight line

Rise is the vertical distance between the two points on the graph. This is measured using the Y axis.
