Answer: y= -1x - 5
Step-by-step explanation:
The equation has to be in slope-intercept form which uses the formula
y=mx+b where m is the slope and b is the y-intercept.
So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.
the x coordinate is -7 and the y coordinate is 2
2 = -1(-7) + b
2 = 7 + b
-7 -7
b = -5 the y intercept is -5
Now the equation will be y= -1x - 5
The number is 90.

What is the number?</h3>
Percentage can be described as the fraction of an amount that is expressed as a number out of hundred. The sign used to represent percentage is %. Percentages are a measure of frequency.
When the number is decreased, the number becomes smaller. This means that the original number is larger than 81.
The equation that can be used to represent the information in the question is:
(1 - percentage decrease) initial number = 81
(1 - 0.1)x = 81
0.9x = 81
x = 81 / 0.9
x = 90

1 jar of paint = 1 pint of paint
This means that Beth has 32 pints of paint.
32 jars of paint = 16 quarts of paint = 4 gallons of paint.
This means that Beth has (or possibly used) 4 gallons of paint.
D=dimes
q=quarters
if she has 12 coins then
12-d=q she has 12-d quarters
we dont know how much money she has unless we know d.
she could have 12 dimes and 0 quarters or 11 dimes and 1 quarter etc. we need more information to solve.
