Support Point-Slope Form Point-slope form: y-y = m(x-x1) An equation of a line can be written in point-slope form given any point ) on the line and the slope of the line Problem A line passes through (-1, 3) and has slope -2. Find an equation of the line. Explain your steps. Step y-y = m(x-x) Written Explanation Use the point-slope form. y-3=-2[x-(-1)] y-3=-2(x+1) Exercises Substitute -1 for x1, 3 for y, and -2 for m. Simplify inside grouping symbols. A line passes through (-3, 4) and has slope. Find an equation of the line. Explain your steps. Step y-y = m(x-x1) y-4=x-(-3)] y-4=(x+3) Written Explanation
