Question

Can someone help me with this math homework please!

Answer 1

1D, 2B, 3A and 4C

Explanation:

→ The slope of a line is the m and the y - intercept is the last number in the y = mx + c :

- Number 1 requires rearranging, but the answer to that is D

- Number 2 is easily identifiable

- Number 3 requires rearranging, but the answer to that is A

- The last option left is c

Answer 2

General eqn in slope intercept form

y= mx+c--------->(i)

where m is slope and c is the y-intercept.

1. y= -x+3

Comparing the above eqn with (i)

m= -1= slope c=3= y-intercept.

Ans.D

2. y=3x-1

m= 3 and c= -1

AnsB

3.y=x-3

m=1, c= -3

Ans A

4.y= 1-3x

or, y= -3x+1

m= -3 and c = 1

Ans C
