What is the equation of the line that passes through (-3,-1 ) and has a slope of 3/5
vfiekz [6]

The point-slope form:

y-y_1=m(x-x_1)

We have the point (-3, -1) and the slope m = 3/5. Substitute:

y-(-1)=\dfrac{3}{5}(x-(-3))\\\\y+1=\dfrac{3}{5}(x+3)\qquad\text{use distributive property}\\\\y+1=\dfrac{3}{5}x+\dfrac{9}{5}\qqua\text{subtract 1 from both sides}\\\\y=\dfrac{3}{5}x+\dfrac{4}{5}\qquad\text{multiply both sides by 5}\\\\5y=3x+4\qquad\text{subtract 3x from both sides}\\\\-3x+5y=4\qquad\text{change the signs}\\\\3x-5y=-4

Answer:

point-slope form: y + 1 = 3/5(x + 3)

slope-intercept form: y = 3/5x + 4/5

standard form: 3x - 5y = -4

Express x^2+8x+15 in the form (x+a)^2-b
IRINA_888 [86]
<h2>'(x+4)^2-1' in the form of (x+a)^2 - b.</h2>

Step-by-step explanation:

We have,

x^2 + 8x + 15

To express x^2 + 8x + 15 in the form of  (x+a)^2 - b = ?

∴ x^2 + 8x + 15

Adding and subtracting 1, we get

= x^2 + 8x + 15 + 1 - 1

= x^2 + 8x + 16 - 1

= x^2 + 2(x)(4) + 4^{2} - 1

Using the algebraic identity,

(x+y)^{2}=x^{2} +2xy+y^{2}

= (x+4)^2-1

Thus, (x+4)^2-1 in the form of (x+a)^2 - b.
