Finding the Slope of a Line Passing through Two Points
With eight pairs of points each, these pdfs offer practice aplenty. Apply the two-point formula, m = (y2 - y1) / (x2 - x1) to find the slope(m) of a line, substituting the two given points: (x1,y1) and (x2,y2) in it.
Converting to the Standard Form
Isolate the x and y-terms to one side and let the constant remain on the other side of the equations as you walk through this set of math worksheet pdfs for grade 8 and write each in the form: ax + by = c.
Convert to the Slope-Intercept Form
Make y as the subject, take its coefficient to the other side, and express each equation in the slope-intercept form: y = mx + b.
Find the Slope using the Slope-Intercept Form
Rewrite each equation in the slope-intercept form and locate the coefficient of x, which is the slope of the line.
Equation of a Line through Two Points: Standard Form
Substitute the x and y coordinates in the equation, (y - y1) / (y2 - y1) = (x - x1) / (x2 - x1), simplify, and rearrange it to the required form.
Graphing a Line through Two Points
Mark the two indicated points on the graph and draw a line that passes through them.
Graph the line: Slope, y-intercept given
Plot the y-intercept; infer the rise and run from the slope and plot another point; connect the two points and graph the line.
Constant of Proportionality | Missing values - Tables
Derive the constant of proportionality(k) by dividing a y-value by its respective x-value and use it to figure out the missing values.
Equate the product of means and product of extremes in each proportion, make the unknown variable the subject, and solve.
Unit Rate Word Problems | Comparing Unit Rates
Read each word problem with 2 or 3 scenarios, find the unit rates for each, and compare them to draw the apt conclusion.
Finding the Equation of a Line using the Intercepts
Determine the equation of a line in standard form using the given x and y intercepts. Word problems are incorporated to enhance variety in problem-solving.
Equation of a line in y = mx + b Form using Point-Slope
Plug the slope(m) and the point(x1,y1)in the equation, (y - y1) = m(x - x1) and rewrite it in the slope-intercept form, y = mx + b.
