Slope is 3 that passes (-2.5)

Question

Find the slope intercept form of the line whose slope is 3 that passes through the point (-2,5)

Answer 1

Given the slope intercept form  y = mx + b

Where m is the slope of the line and (0,b) is the y-intercept

 

We have the slope  m = 3

We can use the given point (-2,5) as our (x,y) values to find b

 

5 = 3(-2) + b

5 = -6 + b

b = 11

 

The equation of the line in slope intercept form is  y = 3x + 11

Answer 2

Slope-intercept form is usually written as y=mx+b.  Using the info given, if you plug in the slope for m, and the x and y values from the point, then you can solve for b and write the equation (remember that when you write your final answer, both m and b should just be numbers, and x and y will go back to being x and y).
