Answer:

Slope = -1

Step-by-step explanation:

You are provided with two points on the line (-5, 7) and (1,1).

$Slope = \frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

$Slope = \frac{7-1}{-5-1} =\frac{6}{-6} =-1$

Answer:

-1

Step-by-step explanation:

rise = -2

run = 2

Slope = rise / run

= -2/2 = -1

Since also the angle made by the line and x axis in anti clockwise direction is > 90° the slope will be-ve .

Find the difference between 7 1/2 and 2 3/4

NNADVOKAT [17]

Answer:

4 $\frac{3}{4}$ or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7 $\frac{1}{2}$ = $\frac{15}{2}$ and 2 $\frac{3}{4}$ = $\frac{11}{4}$

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply $\frac{15}{2}$ x2, it'll equal the same number.

So now we have $\frac{30}{4}$ - $\frac{11}{4}$ , 30-11= 19.

$\frac{19}4}$ simplified is, 4 $\frac{3}{4}$ .

As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.

I hope this helps you!

{y=-x+1 {y=4x-14 please help me my paper is due today

Temka [501]

$- x + 1 = 4x - 14 \\ - x - 4x = - 14 - 1 \\ - 5x = - 15 \\ x = 3$

Substitute x = 3 in any given equations. I will do in y = - x + 1

$y = - x + 1 \\ y = - 3 + 1 \\ y = - 2$

Therefore the answer is (3,-2)
