y = kx is the formula for direct variation

8 = k*20

divide by 20

8/20 =k

divide by 4

2/5 =k

y = 2/5 x

formula: y = 2/5x

b) y=2/5x

y = 2/5 *7

y = 14/5

or as a mixed number 2 4/5

Write the equation for each line. (will give brainlest)

poizon [28]

Answer:

y = $\frac{2}{3}$ x + 1

Step-by-step explanation:

The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 3) and (0, 1).

Slope = $\frac{3-1}{3-0}$

= $\frac{2}{3}$

Thus, the slope of the line is $\frac{2}{3}$ .

Based on the graph, the y-intercept is 1.

Thus, the equation of the line is: y = $\frac{2}{3}$ x + 1.
