Please help I really don’t understand this

Vinil7 [7]

You input the values and the equation would end up as

-5 = -3/2 (6) + b

You use y = mx + b

Y is -5
M is the slope = -3/2
X is 6
B is the y intercept but that is not given

Multiply. (−23)(54) Enter your answer as a fraction, in simplified form, in the box.

Sati [7]

Answer: $-\frac{1242}{1}$

Step-by-step explanation:

By definition, negative numbers, positive numbers and zero are Integers.

It is important to remember the multiplication of signs:

$(-)(-)=+\\(+)(+)=+\\(-)(+)=-$

You can observe that you must multiply two integers, one of them is negative and the other one is positive. The product will be an integer. Then:

$(-23)(54)=-1242$

Since any Integer can be written as a fraction, you can rewrite the product by writing $-1242$ as the numerator and $1$ as the denominator.

Then, this is:

$=-\frac{1242}{1}$

The equation of line m is 4x+5y=−2. What is the slope of a line that is perpendicular to line m?

TiliK225 [7]

Convert to slope / intercept form:-

4x + 5y = -2
5y = - 4x - 2
y = -4/5 x - 2/5

the slope of this line is -4/5 and slope of line perpendicular to it is - 1 / -4/5

= 5/4 answer
