Determine whether the two ratios are proportional. 6/36 and 1/6 a) yes b) no

Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)

Step-by-step explanation:

(7, 8) and (3, -4)

y2 = -4, y1 = 8, x2 = 3 and x1 = 7

Slope m = {y2-y1}/{x2-x1}

m = {-4 - 8}/{3 - 7}

m = -12/-4

m = 3

And

y - y1 = m(x - x1)

y - 8 = 3(x - 7)

y - 8 = 3x - 21

y = 3x - 21 + 8

y = 3x - 13
