Question

Write the equation of the line that passes through (4,2) and has a slope of -2 in

POINT SLOPE FORM. y - y1 = m(x - x1)

Answer 1

y = -2x + 10

Explanation:

The equation in point slope form is expressed using the equation

y - y1 = m(x - x1) where;

m is the slope = -2

(x1, y1) is the point on the line = (4,2)

Substitute into the formula:

y - 2 = -2(x - 4)

y -2 = -2x + 8

y = -2x +8 +2

y = -2x + 10

Hence the required equation of the line is y = -2x + 10
