Point slope form: y - y1 = m(x - x1)
(x1, y1) = a point
m = slope
We are given:
(x1, y1) = (1, 2)
m = 3/2
Put into the original equation:
y - 2 = 3/2(x - 1)
Best of Luck!
Given:
32 bolts for a total of $12.00
3-inch bolt costing 36 cents or 0.36
4-inch bolt costing 42 cents or 0.42
let x represent 3-inch bolt costing 36 cents
let y represent 4-inch bolt costing 42 cents
x + y = 32
0.36x + 0.42y = 12
x = 32 - y
0.36(32-y) + 0.42y = 12
11.52 - 0.36y + 0.42y = 12
-0.36y + 0.42y = 12 - 11.52
0.06y = 0.48
y = 0.48/0.06
y = 8
x = 32 - y
x = 32 - 8
x = 24
James bought 24 pcs of the 3-inch bolt and 8 pcs of the 4-inch bolt.
To check
<span>0.36x + 0.42y = 12
</span>0.36(24) + 0.42(8) = 12
8.64 + 3.36 = 12
12 = 12
I'm not sure if it will work, but try downloading the Slader app. I hear that many people use it to look up text book answers and stuff like that.
