Question 1168791: write an equation of the line in slope-intercept form slope:-1 passes through (4,-7)

y - y1 = m(x - x1) ... Point Slope form
y - y1 = -1(x - x1) ... plugging in the given slope
y - (-7) = -1(x - 4) ... plugging in the given point
y + 7 = -1(x - 4)
y + 7 = -1*x -1*(-4) ... distribute
y + 7 = -x + 4
y + 7 - 7 = -x + 4 - 7 ... subtracting 7 from both sides
y = -x - 3
Answer: y = -x - 3
