AdeyNyx Group Title 7. Write the equation y - 4 = -2(x - 5) in slope-intercept form.(Points : 1) y = -2x + 14 y = -2x + 5 y = -2x + 9 y = -2x + 6 8. If you are finding the line perpendicular to x + 3y = 5, what is the slope of the line?(Points : 1) -3/5 1/3 3 -3 one year ago one year ago

it always works the same way 1) distributive law $y - 4 = -2(x - 5)$ $y-4=-2x+10$ 2) solve for $$y$$ $y=-2x+14$

2. satellite73 Group Title

the slope of $$ax+by=c$$ is $$-\frac{a}{b}$$ in your case the slope of $x+3y=5$ is $$-\frac{1}{3}$$ perpendicular line has slope that is the negative reciprocal

3. satellite73 Group Title

negative reciprocal of $$-\frac{1}{3}$$ is $$3$$
