I don't understand the question. Can I have some context?
Answer:
y = 3x + 1
Step-by-step explanation:
The way you find slope is change in y over change in x, (as a fraction).
So then your equation is y = 3x because the y value goes up 3 times and the x goes up once (3/1), and then you see what value y has when x = 0 to find the b value, which is one.
3x^2+5x-2=?
I think,,,,,
=>3x^2+5x-2=0
=>3x^2+3x+2x-2=0
=>3x(x+1)-2(x+1)=0
=>(3x-2)(x+1)
///////////////??///////////
=>x=2/3 & x= -1
Forgive me if wrong
f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20
