The best way to describe lines y= x+3 and -x+y=7

Mathematics

Alexandra [31]3 years ago

Answer:

Parallel lines

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 = x + 3 ← is in slope- intercept form

with slope m = 1

- x + y = 7 ( add x to both sides )

y = x + 7 ← in slope- intercept form

with slope m = 1

Parallel lines have equal slopes, thus the lines are parallel

Whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
tatiyna

Hey there!

7/4 = 35/m

CROSS MULTIPLY BOTH of your NUMBERS

7(m) = 4(35)

7(m) = 7m

4(35) = 140

NEW EQUATION: 7m = 140

DIVIDE 7 to BOTH SIDES

7m/7 = 140/7

CANCEL out: 7/7 because that gives you 1

KEEP: 140/7 because that gives you the value of m

140/7 = m

Solve above and you have the answer of m

140/7 = 20

Therefore, the value of m = 20

Answer: m = 20

Good luck on your assignment and enjoy your day!
