Answer:
or
Step-by-step explanation:
To write the equation of the line using a slope and a point, use the point-slope formula 
. Here m is 3/7. And the point 
is (4,9). Substitute the values and simplify.
Both the point slope form and the final simplified form are considered equations of the line.
Answer:
1 5/12
Step-by-step explanation:
You can do the opposite of this problem to get the answer. 2/3 + 3/4 = 1 5/12. You can confirm this answer by doing 1 5/12 - 3/4. Therefore, 1 5/12 is your answer.
Answer:
f(x) = -4x + 80
Step-by-step explanation:
You are given two points,
(5, 60) and (10, 40)
in order to get the equation, let's use the form slope-intercept form
m = (y1 - y2) / (x1 - x2)
m = (60 - 40) / (5 - 10)
m = 20/-5
m = -4
Get the x intercept
y = mx + b
60 = (-4)(5) + b
b = 60+20
b = 80
so the equation is
y = -4x + 80
f(x) = -4x + 80
