Writing Linear Equations
Master writing linear equations: point-slope, slope-intercept, and real-world problems.
Watch the video for a refresher on how to find the equation using demos. Write an equation of the line that passes through the given point and has the given slope. (Start off in point slope) Question Answer (1,2) , slope: 3 y=3x-1 (-2,2) , slope: -2 y=-2x-2 Write an equation of the line in slope-intercept form that passes through each pair of points. (USE DESMOS! YOU CAN MAKE A TABLE WITH TWO POINTS.) Question Answer (2, -4) and (4, -2) y=x-6 (0, 5) and (4, 1) y=-x+5 (-3, 1) and (-1, -3) y=-2x-5 (0, 4) and (5, -4) y=-4 (-4, -2) and (4, 0) y=1 (-2, -3) and (4, 5) y=4 DANCE LESSONS. The cost of 7 dance lessons is $82. The cost of 11 lessons is $122. Write a linear equation in slope-intercept form where C represents cost and l represents lessons. Then use the equation to find the cost for 4 lessons. Equation Cost for 4 Lessons C=10l+12 52
