What is the equation in slope-intercept form of a line that is parallel to y=−2x+5 and passes through the point (4, 0)?

1 answer:

6 0

Write the equation of the line parallel to y=2x-5 and passes through the point (2,4). Please help ... We must have slope m=2, and we need to find b the y-intercept. ... b is the y intercept when x=0. Let's plug in the point (2,4) to find b. ... ˆ ˜ ° − ± ÷ ⁄ × ƒ ∫ ∑ ∞ √ ∼ ≅ ≈ ≠ ≡ ∈ ∉ ∋ ∏ ∧ ∨ ¬ ∩ ∪ ∂ ∀ ∃

Look at the picture.

$\cos 75^\circ =\frac{x}{25} \\
25 \cos 75^\circ = x \\
25 \times 0.2588 \approx x \\
x \approx 6.47$

The base of the ladder is 6.47 feet from the house.
