Answer:
1
Step-by-step explanation:
y- intercept occurs at x= 0. Thus, the y-intercept of a line can be found by substituting x= 0 into it's equation.
x -y= -1
When x= 0,
0 -y= -1
-y= -1
Divide both sides by -1:
y= -1 ÷(-1)
y= 1
Thus, the y-intercept is 1.
1 inch = 12 miles
so 6 1/2 inches (or 6.5 inches) = 6.5 * 12 = 78 miles <===
You would square 3968 and subtract 1.
There are 4 terms.
The second term and the fourth term have negative coefficients.
Terms are only negative depending on the value of the variables.
