Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

$\displaystyle\\
k = \frac{P_1}{P_2} = \sqrt{ \frac{A_1}{A_2} }=\sqrt{\frac{18}{32}}=\sqrt{\frac{9\times2}{16\times2}}=\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}= \boxed{\bf \frac{3}{4}}$

Enter the slope-intercept equation of the line that has a slope of -5 and y-intercept (0,8)

Genrish500 [490]

Slope-intercept form is y = mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept. Because we are given these values, all we have to do is plug in the given values into the equation for their respective variables.

y = mx + b

y = -5x + 8

Therefore, your answer is y = -5x + 8.

Hope this helps!
