The equation format for a straight line is y = mx + b, where m is the slope and b is the y-intercept, the value of y at x = 0. The slope is the rate of change of the line as x changes values. It is also termed the "rise over the run," of the difference in the value of y as x is changed.
We can calculate the rise/run from the two points. (0,2) and (-4,5). The rise is the difference between the two y values (5 - 2 = 3) and the run the difference in the x values (-4 - 0 = -4). Rise/run is therefore -3/4. This is "m" in the equation.
y = -(3/4)x + b
We need to find b. Input one of the points, (0,2) and solve for b.
2 = -(3/4)*0 + b
b = 2 (the line crosses the y axis when x = 0).
The full equation becomes:
y = -(3/4)x + 2
Answer:
Total price = item price+(8.75% of item price)
=90+(0.0875*90)
=97.875
Hope this helps <3
0.43 is the answer, because 5 rounds up.
Answer:
3
Step-by-step explanation:
To evaluate an expression with a particular value of the variable, put that value where the variable is and do the arithmetic.
__
1/3(-6) +5 = -2 +5 = 3
For x = -6, the value of the expression is 3.
