Graph linear equations using the intercept method by finding the x-intercept (y=0) and y-intercept (x=0), then plot these two points to draw the line.
Graph lines by plotting a point and using rise over run to move, including negative slope, then connect dots to form the line.
Learn to write line equations using point-slope form and convert to slope-intercept form. The lesson covers computing slope from two points, choosing a convenient point, and handling parallel lines.
Apply the midpoint formula to find the exact midpoint between two coordinates by averaging x and y values, with step-by-step substitution and practice problems.
Identify values that make the denominator zero to determine the domain of rational expressions. Apply factoring and the zero product rule to solve for these domain restrictions and examples.
Explore transformations on the coordinate plane by applying stretches and shrinks to x or y values and performing reflections over the x- or y-axis, with stepwise examples using f(x)=√x.
This course covers algebraic topics including graphing linear equations, slope, intercepts, domain and range of functions, midpoint and distance formulas, parallel and perpendicular lines, graphing inequalities, and transformations on the coordinate plane. The course curriculum aligns to content that is common to most high school algebra 1 and algebra 2 courses as well as college level algebra. Content is taught through interactive video lectures that include guided practice problems and the associated live action solutions. The curriculum is organized into 2 chapters (sections), containing a total of 25 video lectures that are approximately 10 minutes in length each. The instructor for this course is a certified math instructor with over 10 years of middle school, high school, and college level teaching experience.
The content of this course is included within our comprehensive beginning algebra and advanced algebra courses.
