Which is the equation of a line with a slope of -1 and a y-intercept of -6? A y = -6x - 1
B y = -x - 6
C y = x - 5
D y = x + 6

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 1 and c = - 6 , then

y = - x - 6 → B

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
