Find the equation of the line specified.
The slope is 3, and it passes through ( -4, -7).

B y = 3x + 5

Step-by-step explanation:

Equation of a line is y - y_1 = m(x - x_1)

We are given

Slope = 3 = m

Points = (-4, -7)

x_.1 = -4

y_1 = -7

Insert the values into the equation

y - y_1 = m(x - x_1)

y - (-7) = 3[x - (-4)]

y + 7 = 3[ x + 4]

Using 3 to open the brackets

y + 7 = 3x + 12

Using this equation of line for the arrangement

y = mx - c

y + 7 = 3x + 12

y = 3x + 12 - 7

y = 3x + 5

Therefore , the equation of the line is y = 3x + 5
