You didn't specify the whole entire question i'm so sorry.
Point-slope form is a different type of way to write a linear equation than slope-intercept (y=mx+b). Point-slope is in this form: y-ypoint=m(x-xpoint)
Point-slope uses a point and the slope (namesake) to make an equation and can be converted to slope-intercept form. For example, if (4, 2) is my point and 2 is my slope, then point-slope form would be y-2=2(x-4). (This can then be solved for y to get slope-intercept)
Remember to use the same point when plugging in for your x and y in the equation, never use two different points.
12x^2 + 16x - 35

Answer:
15-3(3a+b)+5-6b
15 - 9a - 3b + 5 - 6b
15 - 9a - 9b + 5
20 - 9a - 9b
Step-by-step explanation:
15-3(3a+b)+5-6b
Multiple everything inside of the parenthesis by -3.
15 - 9a - 3b + 5 - 6b
Get the variables together by doing -3b-6b
15 - 9a - 9b + 5
Add 5 to 15.
20 - 9a - 9b
Final answer: 20 - 9a - 9b
There is a ratio of 4 cows to 6 ducks.
There are 160 cows and 240 ducks.
