Final answer:
To write an equation in point-slope form for a line, use the formula y - y1 = m(x - x1). Given a point and slope, substitute the values into the equation and simplify to obtain the final equation is y = -3/4x + 5.
Step-by-step explanation:
To write an equation in point-slope form for a line, we use the formula y - y1 = m(x - x1).
Given that the point is (4,2) and the slope is -3/4, we substitute these values into the equation as follows:
y - 2 = -3/4(x - 4)
Simplifying the equation gives:
y - 2 = -3/4x + 3
Finally, we can rewrite the equation in point-slope form as:
y = -3/4x + 5
