Graph the line with slope 2/3 passing through the point (-3,-3)

Yakvenalex [24]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The equation of given line is ~

$y = \dfrac{2}{3} x - 1$

$\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}$

Let's use the point slope form of line to find the equation of given line ~

that is ~

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

$y - ( - 3) = \dfrac{2}{3} (x - ( - 3))$

$y + 3 = \dfrac{2}{3} (x + 3)$

$y + 3 = \dfrac{2}{3} x + 2$

$y = \dfrac{2}{3} x + 2 - 3$

$y = \dfrac{2}{3} x - 1$

Evan said that the difference between two negative numbers must be negative. Was he right?

lesya692 [45]

No he was not right because if you had -7 and -5 the difference is 7 + 5 which equals 12.

The directions: Write an equation in point-slope form of the line that passes through the given point and has the given slope m.

guajiro [1.7K]

Point slope form y- y1 = m(x- x1) coordinates are (2,1) m=2

so the equation becomes y-1= 2(x-2)
