How to find the slope of a line that is parallel to y equals 2x - 3 and runs through the point(-2,0)

Ganezh [65]

Recognize that parallel lines have the same slope. Then:

Method 1: write y = 2x + c and find c from the given information:

y = 2x + c becomes 0 = 2(-2) + c, so that c = 4. Then y = 2x + 4 (answer)

Method 2: Slope is 2 and a point on the line is (-2,0):

Use the point-slope formula: y - 0 = 2(x+2), or y = 2(x+2), or y=2x+4 (ans)

Write an equation of the line that passes through the given point P and

dexar [7]

Answer <u>(assuming it can be in point-slope form)</u>:

$y-4 = 3(x+2)$

Step-by-step explanation:

Use the point-slope formula $y-y_1 = m (x-x_1)$ , to write the equation of the line in point-slope form. Substitute x and y values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute 3 for it. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, take the x and y values of point P and substitute them into the equation as well. Substitute -2 for $x_1$ and 4 for $y_1$ . This gives the following answer:

$y-4 = 3(x+2)$
