What is the equation of the line with an x-intercept of -1 and a y-intercept of 2?

Mathematics

Radda [10]3 years ago

Answer:

y = 2x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 2) ← coordinates of intercepts

m = \frac{2-0}{0+1} = 2

Note the line crosses the y- axis at (0, 2) ⇒ c = 2

y = 2x + 2 ← equation of line

The list of equations is shown in the picture which equation has No Solution, One Solution, and Infinitely Many Solutions.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have given a linear equation in one variable.

\rm \dfrac{1}{2}y + 3.2y = 20

After solving:

y = 5.40   (one solution)

\rm \dfrac{15}{2}+ 2z -\dfrac{1}{4}=4z+\dfrac{29}{4}  -2z

After solving:

\rm \dfrac{15}{2} -\dfrac{1}{4}=\dfrac{29}{4}

\rm \dfrac{29}{4}=\dfrac{29}{4} (Infinitely Many Solutions)

3z + 2.5 = 3.2 + 3z

2.5 = 3.2  (no solution)

Similarly, we can identify which equation has No Solution, One Solution, and Infinitely Many Solutions.

Thus, the list of equations is shown in the picture which equation has No Solution, One Solution, and Infinitely Many Solutions.
