a wall map is 45 cm high and 27 cm wide. ashley wants to proportionately shrink it so its height is 12 cm. how wide would it be then?

it would be 7.2cm

because

45÷12=3.75

so thats the scale you use

and 27÷3.75 equals 7.2

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
