3 times a number (x) minus y equals y plus 2 times x all multiplied by 5
If a polynomial has more than one variable, then the degree of that monomial is the sum of the exponents of those variables. In this polynomial, 24xyz, the degree is 3 because the sum of degrees of x, y and z is 1 + 1 + 1 = 3.
Answer:
<h2>11x - y = -79</h2>
Step-by-step explanation:
The standard form of an equation of a line:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
We have the points (-7, 2) and (-8, -9). Substitute:
Convert to the standard form:
<em>use the distributive property </em>a(b + c) = ab + ac
<em>add 2 to both sides</em>
<em>subtract 11x from both sides</em>
<em>change the signs</em>
