Answer:

x + y = 15

y = 3x + 1.5

x + (3x + 1.5) = 15

Step-by-step explanation:

Let :

Soft ball practice = x

Soccer practice = y

y = 3x + 1.5

Total practice time :

x + y = 15 - - - (1)

x + 3x + 1.5 = 15

4x + 1.5 = 15

The equation for line r can be written as y=-1/4x+3. Line s which is parallel to lone r includes the point (-4,3). What is the e

MaRussiya [10]

Answer:

$y=-\frac{1}{4}x+2$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope of line S using line R (m)

$y=-\frac{1}{4} x+3$

We can identify clearly that the slope of the line is $-\frac{1}{4}$ , as it is in the place of m. Because parallel lines always have the same slope, the slope of line S would also be $-\frac{1}{4}$ . Plug this into $y=mx+b$ :
