Find the slope of a line that is parallel and the slope of a line that is perpendicular to each line whose equation is given. Pl

aleksley [76]

The equations above are all in the format $y = mx + c$ , where $m$ = the gradient, or slope.

So, in the first question, $y = 4x + 2$ , the gradient would be 4, because 4 is $m$ in this equation (the number before the $x$ ).

The gradient of a line perpendicular to this line is equal to the negative reciprocal of the gradient of the line. A better way to explain it is if $m$ = the gradient of the line and <u /> $m'$ = the gradient of the perpendicular line then:
$m' = - \frac{1}{m}$

So in the first question, the gradient of the perpendicular line is $- \frac{1}{4}$ .

number 3 says,"If u and v are the measures of complementary angles such that sin u =2/5 and tan v =(square root of 21) 21/2, lab

vodomira [7]

Answer and Explanation:

Using trig ratios, we can express the given values of sin u and tan v as shown below

$\begin{gathered} \sin u=\frac{opposite\text{ of angle u}}{\text{hypotenuse}}=\frac{2}{5} \\ \tan v=\frac{opposite\text{ of angle v}}{\text{hypotenuse}}=\sqrt[]{21} \end{gathered}$

So we can go ahead and label the sides of the triangle as shown below;

We can find the value of u as shown below;
