Answer:

a. y = (3/5)× x +1

Step-by-step explanation:

y= mx+c

m = (13-4)/(20-5) = 9/15 = 3/5

c= 1

so, y= mx+c becomes y= (3/5) × x +1

The points in the table lie on a line. Find the slope of the line.

maria [59]

The slope of the line is $-\frac{3}{4}$

First, you must find 2 points.

(-6,8) (-2,5)

Then, you must substitute the value of the points in.

$\frac{5-8 }{-2+6}$

Finally, simplify the fraction.

$-\frac{3}{4}$
