To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

The slope and intercept of a straight line. In the equation y = mx + c the value of m is called the slope, (or gradient), of the line. It can be positive, negative or zero. Lines with a positive gradient slope upwards, from left to right. Lines with a negative gradient slope downwards from left to right.

The graph of a linear equation in two variables is a line (that's why they call it linear ). If you know an equation is linear, you can graph it by finding any two solutions. (x1,y1) and (x2,y2) , plotting these two points, and drawing the line connecting them.

Step I: Take a point M on the y-axis in the positive direction of the y-axis such that OM = 5. Step II: Through M draw a line MN parallel to the x-axis. Step III: Draw a line MP through M such that the line makes an angle 60° with MN (positive direction of the x-axis). This is the required graph of y = 221a3x + 5.

The graph of the linear equation is a set of points in the coordinate plane that all are solutions to the equation. If all variables represent real numbers one can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.

You can simply plot x and y using graph.You can first select the data and then go to insert > recommended charts and select line chart to display it like this:Now, if you wish to find the m and c, simply add a trend-line by right clicking on the blue line.More items...

Slope Formula Here we take a point (0, c) on the y-axis, and an arbitrary point (x, y) on the line. With these two points, we aim at finding the slope 'm' of the line. The slope of the line is the difference of the y coordinates of the two points, divided by the difference of the x coordinates of the two points.
