It’s y intercept is -14 and crosses the x axis at 6
answer: y = 1.5x - 5.5
explanation:
use y = mx +b to model your equation
(m = slope, b = y-intercept)
let's start by finding slope
to find slope, subtract the y values over the x values.
- 4 - (-1) / - 5 - (-3)
solve and simplify.
-3 / -2
two negatives equals a positive, so convert into a decimal and remove the negative
you get 1.5.
now, plug the slope a y and x value into the equation to find b, the missing value.
-1 = 1.5(3) + b
-1 = 4.5 + b
-5.5= b
so, your equation is y = 1.5x - 5.5.
Answer: a good amount

Let s be the cost of one shirt and t, the cost of 1 tie
Then:
(a) 3.s + 5.t = 60
(b) 2.s + 3.t = 39
Solve this equation by elimination:
<span> Let's eliminate t. To that end you multiply all the terms of (a) by negative 3 and all the terms of (b) by positive 5
</span>(a) 3.s + 5.t = 60→→ (-3).(3.s+5.t) → - 9.s - 15.t = -180(c)
(b) 2.s + 3.t = 39→→ (+5).(2.s+3.t) → +10.s + 15.t = 195 (d)
Now you add (c) + (d) → s= $15 , This is the cost of 1 shirt. To find the cost of 1 tie, you replace s by 5 in any of the equation, say (b):
(b) <span>2.s + 3.t = 39 </span>→ 2.(15) + 3t = 39 → 30+3t = 39 and 3t =39-30 = 9
So 3t = 9 and t = $3 (price of 1 tie)
