Final answer:
To write an equation in point-slope form, use the formula y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point. For slope = 4 and point (3,8), the equation is y - 8 = 4(x - 3). For slope = - and point (5, -3), the equation is y - (-3) = -(x - 5).
Step-by-step explanation:
To write an equation in point-slope form, we can use the formula y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point on the line.
For the first question, the slope is 4 and the point is (3,8).
Substituting the values into the formula, we get y - 8 = 4(x - 3).
Similarly, for the second question, the slope is - and the point is (5, -3).
Plugging in the values, we get y - (-3) = -(x - 5).
