Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation for example : -8-7x+-5(4)=0 . But the zero turned to -1 because a non zero constant never equals 0,but the problem doesn’t have a solution, but the answer is -1
Answer:
14/4
Step-by-step explanation:
To find slope, use the equation (y2-y1)/(x2-x1). In your case, the equation is going to look like (-3 - -1)/(5 - -2) or (-3 +1)/(5 + 2), and that simplifies to -2/7.
So this is our table:
-----------------
x-values | a b c d e f |
-----------------
y-values | g h i j k l |
-----------------
You can know that the values in the table are proportional if:
