Question

What are the intercepts of y = -0.75x + 3.0?

Answer 1

\(\Large\color{blue}{ y = -0.75x + 3.0}\) compare to \(\Large\color{blue}{ y = mx + b}\) where ` b` is the `y-intercept`.

Answer 2

To find the x-intercept, you would need to plug in `0` instead of `y` and solve for x.

Answer 3

What does mx mean?

Answer 4

m is just a number.

Answer 5

mx means m × x

Answer 6

ok thanks for your help,but out of (4, 0) and (0, 3)

(2, 0) and (0, 6)

(12, 0) and (0, 3)

(6, 0) and (0, 1)....what would be right?

Answer 7

looks like x-intercept is the first option point, and the second point is the y-intercept.

What do you think is the ` b ` in your equation (looking at and comparing with ` y=m x + b` )?

Answer 8

i keep getting (4, 0) and (0, 3)

Answer 9

yes, correct !

Answer 10

Thanks for your help!

Answer 11

Anytime !

Answer 12

How about y = 4x − 2?

Answer 13

y = 4x -2

Y-intercept
y = 4x -2
y = 4(0) -2
y=-2

X-intercept
y = 4x -2
(0) = 4x -2
0=4x-2
0 \(\normalsize\color{blue}{ +2 }\) =4x-2 \(\normalsize\color{blue}{ +2 }\)
2=4x
2 \(\normalsize\color{blue}{ \div 4 }\) =4x \(\normalsize\color{blue}{ \div 4 }\)
½ =x
