Answer:
6 grapples
Step-by-step explanation:
x = number of wins
y = number of ties
y = 15 - x
48 = 5x + 2y
48 = 5x + 2(15 - x)
48 = 5x + 30 - 2x
48 = 3x + 30
18 = 3x
x = 6

The point-slope form:

m - slope
(x₁, y₁) - point
The formula of a slope:

We have the points (-2, 7) and (1, 1). Substitute:

<em>point-slope form</em>
<em> slope-intercept form</em>
<em>standard form</em>
