Start with the simplest equation of a straight line: y = mx + b.
Subst. 1 for m, 2 for x and 4 for y. Then, 4 = 1(2) + b, or b = 2.
In slope-intercept form, the equation of this line is y = x + 2.

Answer: c 6
Step-by-step explanation:
3 2/3 +2.3...
2.3....=2 1/3
3 2/3 + 2 1/3= 5 3/2
=6
For the first expression we will only simplify the constants:
4b - 24 + 19 ——> 4b - 5
The second expression only has variables so we simplify the whole expression
4p - 5p - 30p = -31p
The third expression we will only simplify the variables
4.2v - 5 - 6.5v ——> -2.3v - 5
