Solution:

The point slope form of a line is given as:

Where, m is the slope of line

From given,

m = -10

Given point is (1, 4)

Substitute m = -10 and = (1, 4) in given formula

Thus the point-slope equation of the line with slope -10 that goes through

the point (1,4) is found

Thus Option D is correct

i just took the test, the correct answer is .. 31.5 in.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
