Solving for y gets:

y=-2/3 X -5/3

so slope is -2/3

y=-2/3 X -5/3

so slope is -2/3

It's a vertical line so the slope is infinite.

The value of f is -7

Slope is usually designed by the letter m. m=delta y/delta x or change in y/change in x or (y2-y1)/(x2-x1).

What we know.

m = -17 (very very steep, with a negative slope, going up to the left)

Point (5, -3)

Point (u,-1)

Putting everything into the above equation, we get

m = (-3-(-1))/(5 - u) , where m =-17

-17 = (-3 + 1)/(5 - u)

-17 = (-2)/(5-u)

To get rid of the fraction, multiply both sides by (5 - u)

-17(5-u) = -2

-85 + 17u = -2

Add 85 to both sides to get rid of the -85.

-85 + 85 +17u = -2 + 85

17u = 83

Divide both side to get u by itself.

17u/(17) = 83 / 17

u = 4.89 (rounded to 2 decimals)

Good luck,

Paul

Let's break this down into a few parts first.

Slope intercept form is otherwise known as y = mx + b, where m is the slope and b is the y-intercept.

Parallel means that the two lines will never meet. They are parallel to each other. In math terms, their slopes are the same, so the m values must be the same.

Starting with y = -5x + 1, putting into slope intercept form, y = mx + b, m = -5 and b=1.

Since it is parallel, it must have the same slope and the m values are the same.

So, y = -5x + b, but we don't know what the value of b is. To determine this, we know the point (-4,-6) is on the line that we are trying to find, so we can substitute it into the equation and calculate b to make it work.

Every time we see an x we put in -4 and every time we see a y, we put in -6.

-6 = -5(-4) + b

-6 = 20 + b

subtract 20 from both sides

-6 - 20 = 20 + b - 20

-26 = b

Now substitute this into the equation.

y = -5x + -26

Putting it into correct form, we get y = -5x - 26.

Let's check it to see if it is correct.

It has a slope of -5, so it is parallel to y=-5x + 1

Is the point (-4,-6) on the line? Let's substitute it in to see if it is on the line.

Again, everywhere we see an x, we put in -4 and everywhere we see a y we put in -6.

-6 = -5(-4) - 26

-6 = 20 - 26

-6 = -6

Sorry for the very long explanation, but after you do a few of them, you will be able to knock them off in minutes.

Good luck,

Paul

Simplify and put it into slope-intercept form:

y=9x-15

From the above the slope is readily seen to be 9 and the y-intercept is -15.

If this is homework be sure to show your work.

slope of side lm by applying slope =(y2-y1)/(x2-x1)

slope of lm=0

slope of mn=5/-3 = -5/3

slope of ln= 5/3

so sum of slopes =0

slope of lm=0

slope of mn=5/-3 = -5/3

slope of ln= 5/3

so sum of slopes =0

difference in y (Y2-Y1) divided by difference in x (X2-X1). Example: 1st point (5,3) and second point (10,6) means subtract 3 from 6 (2nd y value from first)= 3- this is your numerator. now subtract second X value from firt X value (10-5)= 5; this is the denominator. the slope (m) is 3/5 or .6
