Practice Problems

Find slope(m) and Y-intercept(b)
Make sure to write in standard form, y = mx + b for each
problem
1. y = 7x + 9
2. y=-5x-2
3. y = 3x + 1

Answer 1

1. slope is 7 and y-intercept is 9

2.slope is -5 and y-intercept is -2

3. slope is 3 and y-intercept is 1

Explanation:

The standard equation of a line in slope form is;

y=mx + b where m is the slope and b is the y intercept.

In question 1.

y=7x + 9

slope is 7 and y-intercept is 9

In question 2

y= -5x - 2

slope is -5 and y-intercept is -2

In question 3

y= 3x + 1

slope is 3 and y-intercept is 1
