The first one is cost of jam $4, cost of soup $7
ANSWER

EXPLANATION
The required equation passes through:
(4,3) and is perpendicular to x+y=4.
Rewrite the given equation in slope-intercept form:

The slope of this line is -1.
The slope of the required line is perpendicular to this line, so we find the negative reciprocal of this slope.

The equation of the line can be found using:

We substitute the slope and point to obtain:

We simplify to get:


The required equation is
It's sometimes true.
One example is the least common multiple of 2 and 3 is 6, which is their product.
But the product isn't always the answer because (example 2:) the least common multiple of 6 and 10 is 30 because 6*5=30 and 3*10=30, however 6*10 is 60.
Ergo, it is only sometimes true.

Answer:
Y=4x+9
Step-by-step explanation:
Use rise over run to find 2 points for the slope. B is as simple as looking where the line passes y.
