Given expression:
2x(x + 7)-(3x +1);
To distribute implies to spread a process equally in an expression. Often times, the distributive property is used for expressions inside parentheses;
2x(x + 7)-(3x +1)
Distribute 2x over the first parentheses;
the negative sign distributes over the second part
= (2x² + 14x) - 3x -1
= 2x² + 14x -3x -1
Add like terms;
= 2x² + 11x -1
This expression 2x² + 11x -1 is equal to the given one

Answer:
Slope = -
Y-intercept = 4
Step-by-step explanation:
-> See attached
-> This equation is in slope-intercept form.
[] When we use y = mx + b, the m is the slope and the b is our y-intercept.
