Answer:
H y +268 = 12(x +20)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
The first point in the table is (x, y) = (-20, -268), so the equation with these filled in is ...
y -(-268) = m(x -(-20))
y +268 = m(x +20) . . . . . . matches F or H
We can see that the values of y change by a lot more than the values of x. That means the slope is a lot more than 1. This observation eliminates choice F, so we are left with ...
H. y +268 = 12(x +20)
Answer:
Step-by-step explanation:
To find the slope of the line , we will write the equation in the form:
where:
slope
y - intercept.
To write in this form , we will make y the subject of the formula.
Subtract 4x from both sides
Divide through by 2

Answer:
7a + 2b
Step-by-step explanation:
Given
4a + 3b + 3a - b ← collect like terms
4a + 3a + 3b - b
= 7a + 2b
