y – y1 = m(x – x1) is the Point-Slope Form of a linewhere (x1, y1) is a point the line passes throughand "m" is the slope of the line. y = mx + b is the Slope-Intercept form of a line"m" is the slope, and "b" is the y-intercept. Practice with Point Slope and Slope Intercept Forms of Lines Select the Point-Slope form of a line Ax + By = C y = mx + b y - y1 = m(x - x1) Select the Slope-Intercept form of a line y - y1 = m(x - x1) Ax + By = C y = mx + b Write the equation of the line in slope-intercept form: given a y-intercept of 3 and a slope of -2. y = y = mx + b x + Write the equation of the line in point-slope form, of the line passing through the point: (4, 2) and with a slope of 5. y – = (x – ) y - y1 = m(x - x1) Write the equation of the line in point-slope form, of the line passing through the point: (-3, 1) and with a slope of ½. y – = (x + ) y - y1 = m(x - x1) Write the equation of the line in point-slope form: given (-1,8) and the slope of 2. y - y1 = m(x - x1) Write the equation of the same line in slope-intercept form: Write the equation of the line in point-slope form: passing through (0, 5) with a slope of 3. y - y1 = m(x - x1) y = mx + b Determine the slope of the line. Given the slope of 1/4 and the graph, what is the equation of the line? y = 4x + 1 y - 1 = ¼(x - 2) y - 2 = ¼(x - 1) y - 1 = 4(x - 2) y = mx + b Rewrite in slope intercept form: y - 3 = 2(x - 5) Choose the equation of the graph y = (2/3)x y = (-2/3)x y = (-3/2)x y = (3/2)x y-intercept = Slope= y-axis Equation: x = -1 y = -1 x-axis Write the equation of the linein slope-intercept form: Consider the line that passes through the points. (2, 3) and (4, 7) Write the equation of the line, in slope-intercept form: y = x + |
