Answer: The y intercept is -7 or (0,-7)

Step-by-step explanation:

First convert the equation into slope intercept form .

y - 3 = -2(x + 5) Multiply on the right side

y -3 = -2x - 10 Add 3 to both sides

+3 +3

y = -2x - 7

In this case the y intercept is -7 and it is when x is zero.

Jim smith is a salesman who receives a 1,100 draw per week. He receives a 12% commission on all sales. Sales for Jim were 205,00

Sliva [168]

$\bf {{ a}}\%\ of\ b \implies \cfrac{{{ a}}}{100}\cdot b\implies {{ a}}\div 100\cdot b\\\\
-----------------------------\\\\
thus
\\\\
{{ 12}}\%\ of\ 205,000 \implies \cfrac{{{12}}}{100}\cdot 205,000\implies {{ 12}}\div 100\cdot 205,000$
