Identify the slope and y-intercept of the graph in the equation.

y = 5/4 + 1

A. Slope: 5/4 ; y-intercept: -1
B. Slope: 5/4 ; y-intercept: 1
C. Slope: 4/5 ; y-intercept: -1
D. Slope: 4/5 ; y-intercept: 1

y = -5/4 x + 1

A. Slope: -5/4 ; y-intercept: -1
B. Slope: -5/4 ; y-intercept: 1
C. Slope: -4/5 ; y-intercept: 1
D. Slope: -4/5 ; y-intercept: -1

Answer 1

Answer 2

@cwrw238

Answer 3

ok, well first remember y=mx+b. m is slope, and b is y intercept. does this help?

Answer 4

can you help me step by step with the first question so I get the hang of it? @DuckDynastyfan923

Answer 5

ok! so y=5/4x + 1. since 5/4 is where m would be in y=mx+b, this means that 5/4 is your slope. then, since 1 is where b would be in y=mx+b, this means that 1 is your y intercept.

Answer 6

@Vivid are you still here?

Answer 7

SO it would be D then?

Answer 8

yes!

Answer 9

oh wait no it would be B

Answer 10

Wait,, I meant to put the 1st question as 4/5 not 5/4 @duc

Answer 11

SO now it would be D correct?

Answer 12

@DuckDynastyfan923

Answer 13

no, because it says 4/5. the slope is 5/4.

Answer 14

The answer is B, because it says that the slope is 5/4, and that the y intercept is 1.

Answer 15

Wait, The first question is actually: y = 4/5 x + 1

Is it still B? @DuckDynastyfan923

Answer 16

oh, then it is D.

Answer 17

ok, cause when i saw it was 4/5 i was sure it wad D. then.

So the 2nd Question is A correct? @DuckDynastyfan923

Answer 18

no, because a shows a negative y intercept. you want one with a positive y intercept, because the one is postitive.

Answer 19

Ok I get it now thanks @DuckDynastyfan923

Answer 20

no problem! :)
