Answer: the answer is -1
Step-by-step explanation:
Since you know what 4×5 is you just have to use the same answer
Answer: y + 1 = 2 (x -1)
Step-by-step explanation:
Point slope form is:
y - y1 = m (x - x1)
Point on the line is (1, -1) and slope is 2
m = 2
y1 = -1
x1 = 1
y - (-1) = 2 (x - 1) or y + 1 = 2 (x -1)
Your going to have to draw it out,but just look for the number on your number line and put a point above the number.
