Question

help plzzzzzzz

Answer 1

The first one is in slope-intercept form:

y = mx + b

Where 'm' is the slope.

So what's the slope of y = 1.2x + 0.4?

Answer 2

@Justdoitfor

Answer 3

y = mx + b

'm' is slope

y = 1.2x + 0.4

So 1.2 is the slope here.

Answer 4

Now for the 2nd one we have to find the slope.

We can plug the two points they gave into the slope formula:

\(m = \dfrac{y_2-y_1}{x_2-x_1}\)

\(m = \dfrac{10-4}{8-3}\)

What's 10 - 4? @Justdoitfor

Answer 5

it will be 6

Answer 6

Yes, now subtract 8 - 3.

Answer 7

5

Answer 8

Yes, so we have:

\(m = \dfrac{6}{5}\)

Can you divide 6 / 5?

Answer 9

yes 1.2

Answer 10

Okay, so the slopes for both of them are 1.2.

Answer 11

ok thxs so much:)

Answer 12

umm can help me with some more plz?

Answer 13

The first one is y = 1.2x + 0.4, and the y-intercept here is 0.4, because it's in the form of y = mx + b, where 'b' is the slope.

Now we can plug the slope in the 2nd item with one of the points into point-slope form.

\(y - y_1 = m(x - x_1)\)

Where \(y_1\) is the y-value of the point, \(x_1\) is the x-value of the point, and \(m\) is the slope.

So we have:

\(y - 4 = 1.2(x - 3)\)

Distribute 1.2 into the parenthesis:

\(y - 4 = 1.2x - 3.6\)

Add 4 to both sides, what's -3.6 + 4?
