Write an equation in point-slope form of the line that passes through the point (-1,-4) and has a slope of m=-2
Bess [88]

Answer:

y = -2x +6

Step-by-step explanation:

Need to find b, we have 2 points (0,b), (-1,-4) and a slope m = -2

m = (y2 - y1) / (x2 -x1)

-2 = (-4 - b) / (-1 - 0)

Solve for b

-2(-1 - 0) = -4 - b

2 = -4 - b

2 + 4 = b

6 = b

b = 6

Ab is 10. 8 units long if ABC is dilated by a scale factor of k equals 1.3 what is the length of a'b'
Marizza181 [45]
ANSWER


The length of

A'B'=14.04 \: units

EXPLANATION

The object length given to us is,

|AB|=10.8 \: units

The scale factor of the dilation is,

k = 1.3

The image length can be calculated using the formula

|A'B'| = k \times  |AB|

We substitute the given values into the formula to get,

|A'B'| = 1.3\times 10.8


We multiply out to obtain,

|A'B'| = 14.04 \: units
