Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (10, 1) into the partial equation
1 = 30 + c ⇒ c = 1 - 30 = - 29
y = 3x - 29 ← in slope- intercept form
Subtract y from both sides
0 = 3x - y - 29 ( add 29 to both sides )
29 = 3x - y, thus
3x - y = 29 ← in standard form → B
(50-25)/2
25/2
12.5
25+12.5=37.5
Answer:
(-7,-15)
Step-by-step explanation:
We can substitute first y in the second y. Both equations are also functions. We can merge the equations.

Substitute x = -7 in any given equations. I will choose the second equation to substitute in.

<u>Answer</u><u> </u><u>Check</u>
Substitute both x and y in both equations.

The equation is true for (-7,-15).

The second equation is true for (-7,-15).
Therefore our answer is (-7,-15)
