Linear equations and systems worksheets Grade 8
Slope, slope-intercept form, writing the equation of a line, and solving systems by substitution and elimination.
- Finding slope from two pointsFind the slope of the line through two points: change in y over change in x.
- Slope and y-interceptRead the slope and y-intercept from an equation in y = mx + b form.
- Slope and intercept from a graphFind the slope and y-intercept of a line from its graph.
- Writing the equation of a line from a slope and a pointUse the slope and a point to find b and write y = mx + b.
- Writing the equation of a line from two pointsFind the slope from two points, then the y-intercept, and write the equation.
- Standard form to slope-intercept formRewrite Ax + By = C as y = mx + b by solving for y.
- Solving systems of equations by substitutionSubstitute one equation into the other, solve for x, then find y.
- Solving systems of equations by eliminationMultiply so one variable cancels, add the equations, and solve.
