Slope: (y2-y1)/(x2-x1) = m
Find the slope, m, then pick a point, plug in the x, y, and m, and solve for b in the equation:
y = mx + b
That is your y-intercept.
Take out your x and y, plug in m and b, and that is your generic form for your line, t.
B would be the correct answer
Answer:
Move the center of circle A to (1,7), then multiply its radius by 3.
Step-by-step explanation:
Moving the circles to the same center would make them concentric. Then, by multiplying the radius of Circle A by 3, the circle is dilated to the exact size of circle B, since its radius is 9. This shows that Circle B is proportional to Circle A, thus they are similar.
