Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3 A. y - 2 = -3(x + 7)
B. y + 2 = -3(x - 7)
C. y + 7 = -3(x - 2)
D. y - 7 = -3(x + 2)

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (7, - 2 ), thus

y - (- 2) = - 3(x - 7) , that is

y + 2 = - 3(x - 7) → B

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
