Answer:

c) 3

Step-by-step explanation:

The first step is to see if it is positive or negative. since it is going upward and to the right, it is positive, if it is going upward and to the left it is negative. So since it is positive the answer is either a or c. Now that we have our 2 points we need to calculate how far they are. Whenever measuring the distance of 2 points, look how many units it's above or below, then divide by the units it's to the left or right. So for this, it takes 3 points to go up, then 1 point to the side. We don't calculate 1 to the side and 3 down. We always calculate if it goes up and down, and then to the sides.

We find the slope through the formula y2-y1/x2-x1
so when we plug in the values of our two points, we get
2-(-1)/(0-(-1))
this gets us 3/1
Which gives us the slope m=3

a line is paralll yo y=4x-2 and intersects the point (5,-11). what is the equation of this parallel line

victus00 [196]

The equation of line parallel to given line is: y=4x-31

Step-by-step explanation:

Given equation of line is:

$y = 4x-2$

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.

Let m1 be the slope of the given line

then

m1 = 4

Let m2 be the line that is parallel to given line

As we know that the slopes of parallel lines is equal so

m1=m2 = 4

The slope-intercept form of equation of line is:

$y = m_2x+b$

Putting the value of slope

$y = 4x+b$

to find the value of b, putting (5,-11) in the equation

$-11 = 4(5) + b\\-11 = 20+b\\b = -11-20\\b = -31$

Putting the value of b

$y=4x-31$

Hence,

The equation of line parallel to given line is: y=4x-31

What is the mixed number for 88/25?

marysya [2.9K]

SO, first you divide the numerator by the denominator.

Then write it like this: $\frac{88}{12}= \frac{13 +3.25}{25} = 3 \frac{13}{25}.$

The slope of the line below is -4 use the coordinates of the label point to find a point slope equation of the line (4,-9)

zalisa [80]

Point slope form: y1-y2=m(x1-x2)

Given the slope -4 and the set of coordinates (4,-9),

y+9=-4(x-4)

I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.

I hope this helps :)
