Question

Select the correct answer.
What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)?
OA y= 3x + 4
O B. y= 3x - 14
OC. y= 3x-4
OD. y = 3x + 12​

Answer 1

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

$y = mx + b$

where m=3 is the slope .

We substitute the slope to get:

$y = 3x + b$

We substitute the point to find b.

$- 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4$

The equation of the straight line is:

$y = 3x + 4$
