Slope :
---------------------------------------
y = -5x + 2
Slope = -5
---------------------------------------
y - intercept :
---------------------------------------
At (0. 3), y-intercept = 3
---------------------------------------
Equation :
---------------------------------------
y = mx + b
y = -5x + 3
---------------------------------------
Answer : y = -5 + 3
---------------------------------------
supplementary angles add up to 180°.
x = measure of such angle
x + 20 = measure of her sibling.
since "x" has 20 less than her sibling, then clearly her sibling has to have 20 more than "x".

The equivalent expression to given expression is 1/3.
<h3>What is Equivalent Expression?</h3>
Equivalent expressions are defined as algebraic expressions which give the same resulting expression. An algebraic expression (or) a variable expression is defined as a combination of terms by the operations such as addition, subtraction, multiplication, division.
