@TheDream can you help with this one

Answer 4

What are the statements?

Answer 5

A. Graph the first equation, which has slope = 3 and y-intercept = –2, graph the second equation, which has slope = –1 and y-intercept = –4, and find the point of intersection of the two lines

B. Graph the first equation, which has slope = –3 and y-intercept = 2, graph the second equation, which has slope = 1 and y-intercept = 4 and find the point of intersection of the two lines

C. Graph the first equation, which has slope = –2 and y-intercept = 3, graph the second equation, which has slope = –4 and y-intercept = –1, and find the point of intersection of the two lines

D. Graph the first equation, which has slope = 2 and y-intercept = –3, graph the second equation, which has slope = 4 and y-intercept = 1, and find the point of intersection of the two lines.

Answer 6

Equation for a line is y=mx+b where m is slope and b is the y-intercept

Answer 7

yes I know that

Answer 8

So which part is tripping you up

Answer 9

so basically just graph them and explain what it looks like??

Answer 10

The question says just pick a statement which statement follows the rule y=mx+b

Answer 11

graph it and see the intersections baby

Answer 12

Oh ok. Thanks guys

Answer 13

welcome, baby!

Answer 14

help me with one more?

Answer 15

B.5x + y ≥ 2
C.5x – y ≤ 2
D.5x – y ≥ 2

Answer 17

for the 1st one you don't have to graph but you can if you wanted to. the question is just asking for the steps. I think it is just checking if you know the coefficient of the x is the slope and the constant is the intercept. Checking if you know how to do it..

Answer 18

for the 2nd one
one approach is to find the equation first then pick a point and test the solution
here y = 5x - 2 same as 2 = 5x - y
shaded to the right means >
therefore 5x - y >and = 2
example when x = 1 y = 3 y>2
