The slope in the first, second, third, and fourth cases will be 2, -3, 5, and 1, respectively. Then the correct options are A, B, F, and H.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
The slope in the first case will be given as,
m = (1 + 1) / (1 - 0)
m = 2
The slope in the second case will be given as,
m = (1 - 4) / (2 - 1)
m = - 3
The slope in the third case will be given as,
m = (28 - 18) / (4 - 2)
m = 5
The slope in the fourth case will be given as,
m = (-3 + 4) / (1 - 0)
m = 1
The slope in the first, second, third, and fourth cases will be 2, -3, 5, and 1, respectively. Then the correct options are A, B, F, and H.

4x + 3y = 10
9x - 4y= 1
Answers
4x+3y=10 <— you solve for x and get x=5/2-3/4y
then substitute the value of x into 9x-4y=1 to get
9(5/2-3/4y)-4y=1
solve the equation for Y
y=2
now sub the value of y into x=5/2-3/4y
x=5/2 - 3/4 times 2
your answer would be x = 1
therefore you get (x,y) (1,2)
After solving the given equations, the value obtained for x and y will be equal to (1, 2).
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given equations in the question,
4x + 3y = 10 (i)
9x - 4y = 1 (ii)
Multiply equation (i) by 9 and multiply equation (ii) by 4
36x + 27y = 90
36x - 16y = 4
A similar term of x will cancel out from here.
y = 86/43
y = 2
Put y = 2 in equation (i)
4x + 3(2) = 10
4x = 4
x = 1

What are rational and irrational numbers and how are radicals related to rational exponents?
Answers
A rational numbers is any number that can be turned into a fraction/ratio. (Ex. 8, 0.75, 1/3). An irrational number is anything that can't be turned into a fraction/ratio. (Ex. Pi, square root of 2). Radicals and rational exponents are related because radicals can be converted into rational exponents.
Answer:
Any number that can be written as a fraction with integers is called a rational number. An irrational number is a number that cannot be expressed as a fraction for any integers. Radicals are related because for irrational numbers they cannot be simplified under the radical and you use a radical on the exponent to cancel it out, hope this helps!

Method:
X + 21 = 52 is the same as 52 - 21 = x. 52 - 21 = 31 so x = 31
In algebraic equations, you always want to isolate the variable (x) so To do that you would subtract 21 from both sides, and then you would do 52 - 21 = 32
x + 21 = 52
-21 = -21
x = 31
