Answer:
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
