Y=Mx +b
B is 0 because that’s where the graph intercepts the y axis.
M is found by picking any two points and finding the rise and run because m is equal rise/run
Points of choice: (-2,4) and (2,-4)
=2−1/2−1 = -8/4
m is equal -2
Y= -2X
Look at the picture below to differentiate between positive and negative slopes.
Answer:
8 + x = 50, so Jose's saving or x = 42
Hope this helps!
Answer:
b=2.5
Step-by-step explanation:
every point on x axis has y coordinate =0
so bx=10
x=4
4b=10
b=10/4=5/2=2.5
35 = 7 * 5
(7n + 3)(5n + 1)
= 35n^2 + 7n + 15n + 3
= 35n^2 + 22n + 3
so answer is
(7n + 3)(5n + 1)
