Question

The graph below shows the price, y, in dollars, of different amounts of pounds of almonds, x: A graph titled Almond Prices shows Number of Pounds on x axis and Price in dollars on y axis. The scale on the x axis shows numbers from 0 to 12 at increments of 2, and the scale on the y axis shows numbers from 0 to 84 at increments of 14. A straight line joins the ordered pairs 0, 0 and 12, 84 Which equation best represents the relationship between x and y? y = 7x y = x + 7 y = 14x y = x + 14

Answer 1

(0,0)(12,84)
slope = (84 - 0) / (12 - 0) = 84/12 = 7

it goes thru the origin (0,0) therefore, the y int = 0

In y = mx + b form, the slope will be in the m position and the y int will be in the b position.

ur equaton is : y = 7x + 0, which can also be written as y = 7x <==
