Find the value of r so the line that passes through each pair of points has the given slope. (r,3), (5,9), m = 2

Will give brainillest if you show work thank you

(X-x0)m=y-y0

(X-5)2=y-9

2x-10=y-9

2x-1=y

Substitute (r,3) in the equation

2(r)-1=3

2r=4

R=2

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
