Answer:

the scale factor is 3/5

Step-by-step explanation:

Make a fraction by putting the new (scaled image) over the original image.

9/15.

Simplify by dividing each by 3.

3/5.

The scaled image is smaller so your answer has to be less than 1 and greater then 0.

What is the y-intercept for the graph of this line? 3x - 5y = 6 - 6

photoshop1234 [79]

The right side of the equation is 6-6 which equals 0.

So the equation could be written as 3x-5y = 0

Since the right side of the equation is zero both the x and y intercepts are (0,0)

What is a correct equation for the line passing through the point (-2,1) and having slope m=1/2

frez [133]

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

$y-1=\dfrac{1}{2}(x-(-2))$

$y-1=\dfrac{1}{2}(x+2)$ - point-slope form

Covert to the slope-intercept form (y = mx + b):

$y-1=\dfrac{1}{2}(x+2)$ use the distributive property

$y-1=\dfrac{1}{2}x+1$ add 1 to both sides

$y=\dfrac{1}{2}x+2$ - slope-intercept form

Convert to the standard form (Ax + By = C):

$y=\dfrac{1}{2}x+2$ multiply both sides by 2

$2y=x+4$ subtract x from both sides

$-x+2y=4$ change the signs

$x-2y=-4$ - standard form

Convert to the general form (Ax+By+C=0):

$x-2y=-4$ add 4 to both sides

$x-2y+4=0$ - general form
