Question

What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?

y−1=4(x−3)

y+3=4(x+1)

Answer 1

Explanation:

About Point Slope Form:

• Y- Y1 = m (x -X1)
• m is the slope
• Y1 & X1 is a point on the line
• The form allows you to identify the slope & the point on the line

Y - 3 = 4 (x - -1)

Answer 2

The point-slope form:

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

We have the slope m = 4 and the point (-1, -3). Substitute:

`y-(-3)=4(x-(-1))\\\\\boxed{y+3=4(x+1)}`
