I need to explain this how do i do that?

To solve, we need to write this in slope-intercept form.

Slope: 3

Point: (1,2)

Slope-intercept form:

y = mx + b (y = y value, m = slope, x = x value, b = y-intercept)

y = 2, m = 3, x = 2, b = ?

We have to solve for b. To do so, we plug in all these values into our formula. Move all values not equal to b to the left of the equation.

Now that we know what b is, we can plug it into our equation. Plug in only the value of the slope and the y intercept.

y = mx + b

y = 3x - 1

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
