Question

State the slope and y intercept of the equation for these 3 questions

Answer 1

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

(1)

y = 3x + 4 is in this form

with slope m = 3 and y-intercept c = 4

(2)

y = - $\frac{3}{7}$ x - $\frac{1}{7}$ is in this form

with slope m = - $\frac{3}{7}$ and y-in tercept c = - $\frac{1}{7}$

(3)

rearrange 3x + y = - 4 into slope-intercept form

subtract 3x from both sides

y = - 3x - 4 ← in slope-intercept form

with slope m = - 3 and y-intercept c = - 4
