Yes, any two parallel lines have the same slope.

For example, graphing out y = 2x+5 and y = 2x+7 will produce parallel lines (both lines have a slope of 2). The two lines will never cross. Algebraically we can solve this system of equations as follows:

y = 2x+5 ... start with the first equation

2x+7 = 2x+5 ... replace y with 2x+7

2x+7-2x = 2x+5-2x .... subtract 2x from both sides

2x-2x+7 = 2x-2x+5

0x+7 = 0x+5

0+7 = 0+5

7 = 5 ... we have a contradiction and false statement here

Because of the false equation in the last line, the original system mentioned above does not have any solutions. A solution to a system is one where the two lines cross.

Complete the point-slope equation of the line through (2,3 and (7,4). Use exact numbers.

uysha [10]

The point-slope equation of the line is $y-3=\frac{1}{5}(x-2)$

Step-by-step explanation:

The form of the point-slope equation is $y-y_{1}=m(x-x_{1})$ , where

m is the lope of the line
$(x_{1},y_{1})$ is a point lies on the line

The slope of a line $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where

$(x_{1},y_{1})$ and $(x_{2},y_{2})$ are two points on the line

∵ The line through (2 , 3) and (7 , 4)

∴ $x_{1}$ = 2 and $x_{2}$ = 7

∴ $y_{1}$ = 3 and $y_{2}$ = 4

- Substitute these value in the rule of the slope

∵ $m=\frac{4-3}{7-2}=\frac{1}{5}$

∴ the slope of the line is $m=\frac{1}{5}$

Let us substitute the value of the slope and the coordinates of point $(x_{1},y_{1})$ in the form of the equation

∵ $y-y_{1}=m(x-x_{1})$

∵ $x_{1}$ = 2 and $y_{1}$ = 3

∵ $m=\frac{1}{5}$

∴ $y-3=\frac{1}{5}(x-2)$

The point-slope equation of the line is $y-3=\frac{1}{5}(x-2)$

Joe spends $8 for lunch and $6.50 for dry cleaning. He also buys 2 shirts that cost the same amount. Joe spends a total of $52.

faltersainse [42]

2shirts=52-8-6.50=37.50

so each shirt costs 18.75$
