Graphs and equations of lines

Answer:

a) y = -\frac{3}{4} x + 5

b) y = 6x-18

c) y = \frac{4}{5} x+\frac{19}{5}

Step-by-step explanation:

a) The slope / gradient is the coefficient of x, so for a) it will be y=-\frac{3}{4} x + C.

C is the y-intercept, so the full equation will be y = -\frac{3}{4} x + 5.

b) Again, since the slope is 6, we know the coefficient of x will be 6.

Now, we have a point on the line and so far, we know the equation is y=6x+c. The coordinates of the point are (2,-6). So now we substitute the y and x values into the equation in order to find C.

-6 = 6(2)+C

-6 = 12+C

C = -18

y = 6x-18

c) To find the gradient we must use the formula \frac{rise}{run}.

rise = change in y value

run = change in x value

so, the gradient = \frac{7-3}{4-(-1)} = \frac{4}{5}

Now the equation is y = \frac{4}{5} x +C

Again, to find C we substitute any of the coordinates into the equation. I will use (-1,3).

3 = \frac{4}{5} (-1) +C

3 + \frac{4}{5} =C

C =\frac{19}{5}

so c) is y = \frac{4}{5} x+\frac{19}{5}

At a football game, your team lost 55 yards on the first play and then 77 yards on the second play. Which expression gives the t
Aleks04 [339]
The answer is the third one (C?) because if you started at 0, you are going below it since you are losing yards, causing you to have less and less yards. Adding two negatives gives you a lesser amount.

I need to find the least common denominator of x+2/x^2+2x-3 , x-7/x^2+5x+6
grin007 [14]

Answer:

(x + 3)(x - 1)(x + 2)  

Step-by-step explanation:

The fractions are:  

\dfrac{x + 2}{x^{2} + 2x - 3} \text{ and } \dfrac{x - 7}{x^{2} + 5x + 6}

Factor each denominator  

x^{2} + 2x - 3 = (x + 3)(x - 1)\\x^{2} + 5x + 6 = (x + 3)(x + 2)

We must find the least common multiple of the denominators.  We take the maximum power of each separate factor.

      Factors of first fraction = (x + 3) × (x - 1)

Factors of second fraction = (x + 3)             × (x + 2)

                                   LCM = (x + 3)(x - 1)(x + 2)

The lowest common denominator of the two fractions is (x + 3)(x - 1) (x + 2).
