Find the slope of the line whose equation is px - qy = r. q/p p/q -r/q

Zina [86]

Answer:

The slope is equal to

$m=\frac{p}{q}$

Step-by-step explanation:

we have

$px-qy=r$

Isolate the variable y

Subtract $px$ both sides

$px-qy-px=r-px$

$-qy=r-px$

Divide by $q$ both sides

$-y=(r-px)/q$

Multiply by $-1$ both sides

$y=(px-r)/q$

$y=\frac{p}{q}x-\frac{r}{q}$ ------> linear equation into slope-intercept form

the slope is equal to

$m=\frac{p}{q}$

The y-intercept is equal to

$b=-\frac{r}{q}$

Paul's family drove 377 mi to the beach averaging 58 mi/h on the way there. On the return trip home, they averaged 65 mi/h

Jet001 [13]

The answer is 12.3 hours.

On the way to the beach, the family averaged 58 mi/h over 377 mi, so we take 377/58 to find the amount of time spent going to the beach. 377/58 = 6.5 hours.

On the way back, they averaged 65 mi/h over the same 377 mi, so we take 377/65. 377/65 = 5.8 hours.

6.5 + 5.8 = 12.3

Use the intercepts of the following quadratic curve to find its graph.y = -1/2x^2 -3/2x+2

Solnce55 [7]

The correct graph is fourth option

Explanation: $\begin{gathered} \text{The quadratic function:} \\ \text{y = }\frac{-1}{2}x^2\text{ - }\frac{3}{2}x\text{ + 2} \end{gathered}$

Using the intercepts: we have x-intercept and y-intercept

To get x intercept, we will equate the function to zero. That is y = 0

$\begin{gathered} 0\text{ = }\frac{-1}{2}x^2\text{ - }\frac{3}{2}x\text{ + 2} \\ mu\text{ltiply through by 2:} \\ 0=-x^2\text{ - 3x + 4} \\ x^2\text{ + 3x - 4 = 0} \\ x^2\text{ - x + 4x - 4 = 0} \\ x(x\text{- 1) +4(x - 1) = 0} \\ (x\text{ + 4)(x - 1) = 0} \\ x+4\text{ = 0 or x - 1 = 0} \\ x\text{ = -4 or x = 1} \end{gathered}$

x intercepts are x = -4 and x = 1

This means the line will cross the x axis at two points: x = -4 and x = 1

To get y-intercept, we will equate x to zero:

$\begin{gathered} \text{y = }\frac{-1}{2}(0)^2\text{ - }\frac{3}{2}(0)\text{ + 2} \\ y\text{ = 0 - 0 + 2} \\ y\text{ = 2} \end{gathered}$

y-intercept = 2

This means the line will cross the y axis at y = 2

The correct graph is fourth option
