Help!!!! Plssss!!! ASAP
zimovet [89]

Answer:

The y-intercept is (0,-26)

Step-by-step explanation:

Given two points P(a,b) and Q(c,d), the line that passes for both points can be found with the expression

\displaystyle y-b=\frac{d-b}{c-a}(x-a)

We'll take the first two points P(34,-52) and Q(51,-65) to find

y=-\frac{13}{17}(x-34)-52\\ \\y=-\frac{13}{17}x-26

Let's verify if the third point is on the line:

y=-\frac{13}{17}68-26=-52-26=-78

It belongs to the line. To find the y-intercept of the line, we set x to 0

y=-\frac{13}{17}(0)-26=-26

The y-intercept is (0,-26)

Graph the image using the given transformation
love history [14]

1) First find the coordinates of the shape:

G(-1, -2), F(-1, -1), E(2,2), D(2, -2)

2)It asked for dilation of 2 about the origin.

<u><em>*What is dilation?</em></u>

<em>Dilation is the expanding/enlarging a transformation by a scale factor</em>

Now we multiply all the coordinates with the factor of 2

G(-1*2, -2*2) = G'(-2, -4)

F(-1*2, -1*2) = F'(-2, -2)

E(2*2, 2*2) = E'(4, 4)

D(2*2, -2*2) = D'(4, -4)

3) Now plot these points and graph the transformation:
