What is the slope of a line that is perpendicular to the graph of y = –3x?
Morgarella [4.7K]

Step-by-step explanation:

Hey there!

The equation is; y= -3x

or, 3x+y = 0.......... (I)

From equation (I)

slope(m1) =  \frac{ - coeff. \: of \: x}{coeff. \: of \: y}

m1=  \frac{ - 3}{1}

Therefore, m= -3

Now, As per the condition of perpendicular lines;

M1*M2 = -1

-3*M2 = -1

M2= -1/-3

Therefore, the slope of a line which is perpendicular to the equation is; 1/3.

Evaluate 10 m +\frac {n^2}410m+ 4 n 2 ​ 10, m, plus, start fraction, n, start superscript, 2, end superscript, divided by, 4, en
DerKrebs [107]

Evaluate the expression 10m + \frac{n^2}{4} where m=5  and n=4

We replace the value of m and n  to evaluate

m=5  and n=4

10m + \frac{n^2}{4}

10(5) + \frac{4^2}{4}

50 + \frac{16}{4}

50 + 4 = 54

The value of the given expression is 54 when m=5  and n= 4
