Step-by-step explanation:
Note that the line goes through the points 
and 
so we can calculate the slope m of the line as follows:
which makes our equation take the form
To find the value of b, use either P1 or P2. Let's use P1:
Therefore, the equation for the line is
Answer:
4a+5a+7b-b
the first thing is to put the like terms together
Step-by-step explanation:
then add or subtract as given after pairing.
Therefore;
our answer is; 9a+6b
since it is factorisable we can further write it this way; 3(3a+2b)
q2) 6c+4d-c-7d
we first put the like terms together
6c-c+4d-7d
we then add and subtract
5c-3d
since our answer is not factorisable we leavem;
5c-3d as our final answer
Answer:
You can model a data using a linear function when the dependent variable is a multiple of the independent formula plus another constant by the y-intercept. The constant multiple is represented by the slope. In real life problems, linear function is applied when you want to determine the cost given with a slope which is represented by cost per unit time. For example, the cost of wifi connection is $10/month plus $2 inclusive for phone charges. The linear function would be:
C = 10t + 2
where C is the cost and t is time in months

Answer:
To find the area of this right triangle, Diego and Jada used different strategies. Diego drew a line through the midpoints of the two longer sides, which decomposes the triangle into a trapezoid and a smaller triangle. He then rearranged the two shapes into a parallelogram.
