Given :-

Line p has an equation of y = 5/3x - 4 .
Line q includes point (-10,-3) and is perpendicular to the line p .

To Find :-

The equation of line q .

Solution :-

The equation of the line p is ,

$\sf\blue{\longrightarrow}$ y = 5/3x - 4

On comparing to slope intercept form of the line which is y = mx + c , we have ,

$\sf\blue{\longrightarrow}$ m = 5/3

Now as we know that the product of slopes of two perpendicular lines is -1 . So the slope of the perpendicular line will be ,

$\sf\blue{\longrightarrow} m_{\perp} = -3/5$

Now here the line q passes through the point (-10,-3) . So on using the point slope form of the line we get ,

$\sf\blue{\longrightarrow} y - y_1 = m(x-x_1)$

$\sf\blue{\longrightarrow}$ y - (-3) = -3/5[ x-(-10)]

$\sf\blue{\longrightarrow}$ y +3 = -3/5(x+10)

$\sf\blue{\longrightarrow}$ y+3 = -3/5x - 6

$\sf\blue{\longrightarrow}$ y +9 = -3/5x

$\sf\blue{\longrightarrow}$ y = - 3/5x - 9

Hence the required answer is y = -3/5x - 9 .

Mr. T weighs three times as much as his dog, x. When you add the weight of Mr. T to the weight of x,

Helen [10]

Step-by-step explanation:

So if we take 60 as the weight of x then

Mr T weighs = 60 x 3 = 180

T + x = 240

180 + 60 = 240
