Write various of the equation of a line that passes through (-6, 3) and has a slope of - 1/3

pishuonlain [190]

Answer:

$\large\boxed{y-3=-\dfrac{1}{3}(x+6)-\text{point-slope form}}\\\boxed{y=-\dfrac{1}{3}x+1-\text{slope-intercept form}}\\\boxed{x+3y=3-\text{standard form}}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We have

$m=-\dfrac{1}{3},\ (-6,\ 3)\to x_1=-6,\ y_1=3$

Substitute:

$y-3=-\dfrac{1}{3}(x-(-6))\\\\y-3=-\dfrac{1}{3}(x+6)$

Convert to the slope-intercept form

$y=mx+b$

$y-3=-\dfrac{1}{3}(x+6)$ use the distributive property

$y-3=-\dfrac{1}{3}x-2$ add 3 to both sides

$y=-\dfrac{1}{3}x+1$

Convert to the standard form

$Ax+By=C$

$y=-\dfrac{1}{3}x+1$ multiply both sides by 3

$3y=-x+3$ add x to both sides

$x+3y=3$

Please help me with this Algebra problem: The length of a rectangle is 91 less than six times the width of the rectangle. If the

horsena [70]

182 Let x = width then y = 6x - 91. P (perimeter) = 2x + 2y = 84 then

2(x) + 2(6x - 91) = 84 | 2x + 12x - 182 =84 | 14x = 84 + 182 | 14x = 266 | x = 19 cm

y = 6x - 91 | y = 6 (19) - 91 | y = 114 - 91 | y = 23 cm

Check: P = 2x + 2y | P = 2(19) + 2(23) | P = 38 + 46 | P = 84 cm (Checked)
