7/8a=42
a=42*8/7 (times both sides by 8/7 to cancel the fractions)
a=48
Answer:
there are several ways to write, and find slope...see explanation
Step-by-step explanation:
Way 1: slope Intercept- y=mx+b
step 1: find where the line crosses the Y axis(the one running up and down...thats is your "b" so if the line crosses at -2...it would be this: y=mx-2
Step 2:from the point where the line crosses the Y axis, count how many up/down and Left/right to the next point..so if you go up 2 right 1, it would look like this y=2x-2
Up=positive
down=negative
left=negative
right=positive
Answer:
its (0, 0) because the line goes through thex and y intercept
In order to get -140, one number has to be negative and one number has to be positive. And these two numbers when added together give you a -4, which means the greater of these numbers has to be negative.
Try guess and check strategy by listing possible factor combinations for -140 and see which one works!
