Answer:

Step-by-step explanation:

$-3 +\dfrac{1}{3}x - 4.5 -\dfrac{1}{5}x\\\\\\= -3 - 4.5 +\dfrac{1}{3}x - \dfrac{1}{5}x\\\\\\= - 7.5 + \dfrac{1*5}{3*5}x - \dfrac{1*3}{5*3}x\\\\\\= -7.5 +\dfrac{5}{15}x-\dfrac{3}{15}x\\\\\\= -7.5 + \dfrac{5-3}{15}x\\\\\\= -7.5 +\dfrac{2}{15}x$

Write an equation in slope intercept form of the line with the given characteristics:

stiks02 [169]

Answer:

The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7

Step-by-step explanation:

The slope-intercept form of an equation is given by:

$y = mx+b$

here m is the slope of the line and b is the y-intercept

Given

$m = 2$

Putting m=2 in the general form

$y = 2x+b$

In order to find the y-intercept, the given point (-3,1) will be substituted in the equation

$1 = 2(-3)+b\\1 = -6+b\\b = 1+6\\b = 7$

Putting the value of b

$y = 2x+7$

Hence,

The equation of line through (-3,1) and slope 2 in slope-intercept form is: y = 2x+7
