Quadrilateral H prime is the image of quadrilateral H after a sequence of transformations. If quadrilateral H prime is congruent to quadrilateral H, which transformations could have been used? a dilation by a scale factor of 2 followed by a reflection
a rotation followed by a dilation by a scale factor of One-half
a reflection, a translation of 1 unit left, and then a dilation by a scale factor of 3
a translation of 6 units down, a rotation, and then a reflection

step-by-step explanation:

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
