Answer:
Step-by-step explanation:
let an equation of this line : y= ax+b ....a : is the slope
1) the acute angle subtend by it and the line 4+y=0 equal to 45 degree
so : a = tan (45°) =1
so : y = x+b
calculate : b this line passes through point A(2,1) : 1= 2+b
b= - 1
conclusion : y = x -1 color : red 4+y =0 color : bleue

Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- algebra
- algebraic addition subtraction
- PEMDAS
<h3>tips and formulas:</h3>
- quadratic expression standard form:ax²+bx+c
- order of PEMDAS
- parentheses
- exponent
- multiplication or
- division
- addition
- subtraction
<h3>given:</h3>
<h3>to do</h3>
<h3>let's do:</h3>
therefore
we can see the expression is in standard form since a,b and c is -3,6 and -4
also let's justify it
substitute the value of a,b and c respectively
(-3)x²+(6)x+(-4)
-3x²+6x-4 (proven)
