The equation of a line is written as y=mx+b, where the constant m is the slope of the line, and the b is the y-intercept. One of the common algebraic problem questions asked is how to find the line equation from a set of values, such as a table of numbers that correspond to the coordinates of points.
Find the value of 'b' in the slope intercept equation. y = mx + b y = 4x + b Since our table gave us the point (0, 3) we know that 'b' is 3. Remember 'b' is the y-intercept which, luckily, was supplied to us in the table.
Review how to figure out how to find the equation that represents the relationship between the x and y variables given in a function table. This video reviews how to find the equation and express
Graph linear equations using y=mx+b - the slope intercept. What does this mean? All linear equations can be made into an equation of this form - where m is the gradient (slope) of the graph - that
Go to Desmos.com and choose Start Graphing. In the upper left, choose Add Item > table. Type your data in the table. Click on the wrench in the upper right to change the graph settings. Modify your x, and y values to reflect your data. Decide what type of equation the data represents. In the example above, the data appears to be quadratic.
Find the slope intercept equation of a line (y=mx+b or y=mx+c) from two points with this slope intercept form calculator. Coordinates of Point 1 (x1,y1): x=. y=. Coordinates of Point 2 (x2,y2): x=. y=. Fill in the coordinates of two points to calculate the slope intercept.
