Answer:
Step-by-step explanation:
Point-slope form is represented by 
. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.
To find the slope, use the slope formula 
. 
and 
represent the x and y values of one point the line crosses, and 
and 
represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:
Thus, the slope is 
.
2) Now, using the point-slope form of , substitute 
, , and for real values in order to write an equation in point-slope form. The represents the slope, so substitute in its place. The and represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for and . (I chose (8,9)). This gives the following equation and answer:
Answer:
so the final answer is =17
Step-by-step explanation:
9+12/3=13+4/2=2+1*2=2 the answer is 13+2+2=17
Answer:
$300
Step-by-step explanation:
Since 20% is equal to 1/5, you should multiply $60 by 5 to get $300 as the original cost and as your answer.
Answer: 3x + 1 is an expression that is simplified as much as it can be. Therefore, either your question is incomplete or it's a trick question. If so, then the answer is 3x + 1.
