How do you graph the line #y = 4/5x + 3#?
2 Answers
Assign value for x to find y.
Explanation:
If x is zero,
If x is 1,
If x is 2,
etc.
You can graph now:
graph{((4x)/5)+3 [-8.04, 11.96, -2.4, 7.6]}
Refer to the explanation.
Explanation:
Graph:
You only need two points to graph a straight line. The most convenient points are the x- and y-intercepts.
Y-intercept: value of
Substitute
The y-intercept is the point
X-intercept: value of
Substitute
Multiply both sides by
Subtract
Divide both sides by
Switch sides.
The x-intercept is the point
You now have two points plotted. Draw a straight line through the points.
graph{y=4/5x+3 [-10, 10, -5, 5]}
