Answer:
Y=x + 7
slope = 1, the coefficient of the x term, an implicit one
plug the point y=4, x=-3 into the equation, 4=-3+7 = 4, it passes through the point (-3,4)
Step-by-step explanation:

Answer:
-2/3 is the y intercept
Step-by-step explanation:
So to find the y-intercept you must first put this in Slope-intercept form, I believe the form it is in right now is called standard form.
To get it into slope intercept form, we have to isolate y:
subtract 2x from both sides:
-3y = -2x + 2
Divide both sides by -3:
y = (2/3)x - 2/3
Now that we have slope-intercept form, we can find the y-intercept. We know slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In this case the y-intercept is -2/3.
Hope this helps!
deltax = (56-0)/4 = 14
number of intervals 4
The intervals are:
(0,14),(14,28),(28,42),(42,56)
The Midpoint Rule =
f(7)+f(21)+f(35)+f(49)
[0.47577]+[-0.99159]+[-0.35892]+[0.65699]
deltax =14
sum = -0.21774
Multiplying by deltax = -3.0484
