Identify the slope .this can be done by calculating the slope between two known points of the line using the slope formula.
find the y-intercept.this can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b. hope it helps :)
Answer:
(-1,4) is a solution to the system.
Step-by-step explanation:
For this problem, we can simply identify if this point is a solution by verifying the plugged in point values allow the left hand side to equal the right hand side.
(1) -2x - 3y = -10
-2(-1) - 3(4) ?= -10
2 - 12 ?= -10
-10 == -10
(2) -3x + y = 7
-3(-1) + (4) ?= 7
3 + 4 ?= 7
7 == 7
Since both equations are satisfied by this point, then we can say the point (-1,4) is a solution to the system. Additionally, this means this is a crossing point of the system of equations.

So a function would have no equation is just put numbers that don’t creat an equation like 5,3 in one column and another one with 8,2
The sales tax amount is $ 28.4
<em><u>Solution:</u></em>
Given that you purchase an ipod that costs $339
The tax rate is 8.375 %
To find: Sales tax amount
From given,
Cost price = $ 339
Tax rate = 8.375 %
Therefore, sales tax amount is 8.375 % of cost price
Thus sales tax amount is $ 28.4
