Item 1 Write an equation of the line with a slope of 2 and y-intercept of 9
2 answers:
Answer:
y=2x+9
Step-by-step explanation:
always start your equations by writing Y=
y=mx+b
The M will be your slope
the B will be your Y-Axis coordinate
Just plug your numbers in
Y=mx+b the M turns into 2 since that is the new slope
Y=2x+b. The X never changes. It will always be there just for looks.
Y=2x+9. It is now +9 on the end due to that being the coordiante where the line touches the Y-Axis. It would be Y=2x-9 if it was a negative slope.
These rules will ALWAYS work.
Hope this helps!!

Answer:
A. With each 9s fact you add another 9, which means you go straight down a row and back one space. This creates a diagonal pattern in the grid.
The answer is 25
Step-by-step explanation:
We know that all the angles of a triangle add up to 180 degrees.
If J = L then L = J so they will both equal 50 cut in half is 25
