What is the equation of the line in slope-intercept form that passes through point (4, 5) and is parallel to the line y = −2x −

Anestetic [448]

Answer:

$y=-2x+13$

Step-by-step explanation:

Slope-intercept form of a linear equation:

$y=mx+b$

where:

m is the slope
b is the y-intercept

Given equation:

$y=-2x-2$

Therefore, comparing the given equation with the slope-intercept form:

slope (m) = -2
y-intercept (b) = -2

The slopes of parallel lines are equal.

Therefore, the slope of the new line is -2.

Substitute the given point (4, 5) and the slope m = -2 into the slope-intercept formula and solve for b:

$\implies y=mx+b$

$\implies 5=-2(4)+b$

$\implies 5=-8+b$

$\implies b=13$

Finally, substitute the found values of m and b into the formula to create the equation of the line that passes through the given point and is parallel to the given line:

$\implies y=-2x+13$

Answer: x would have to equal 8

Step-by-step explanation: When a line intersects parallel lines it forms supplementary angles. The sum of two supplementary angles is 180°

We can use this information to set up an equation:

(6x -7 ) + (19x -13) = 180 . Combine like terms

25x -20 = 180 Add 20 to both sides.

25x = 200 Divide both sides by 25

x = 8

Check:

19(8) - 13 + 6(8) - 7 = 180

152 - 13 + 48 -7 = 180

139° + 41° = 180

The sum of the interior angles formed by the line is 180°, so lines a and b must be parallel.
