Slope m = (y2 - y1)/(x2 - x1) < (FORMULA)
= (9-3)/(7+5)
= 1/2 or 0.5
Answer:

Step-by-step explanation:
The slope0intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, b)</em>
The formula of a slope:

====================================================
From the graph we have two points:
(0, -5) → <em>b = -5</em>
(5, 1)
Calculate the slope:

Put the value of a slope and of an y-intercept to the equation of a line:

2 x 2 x 2 + 3 x 3 x 3 = 35
