Passing through (1,9),slope=2
Natalka [10]
Passes through (1, 9) with a slope of 2.

Assuming that we want this in slope intercept form, which is y=mx+b (m=slope, b=y-intercept) then we need to find the y-intercept! :)

To find the y-intercept (or b!!) you simply need to plug everything into slope intercept form using our given points.

y = mx + b

Plug everything in.

9 = 2(1) + b

Simplify.

9 = 2 + b

Subtract 2 from both sides.

9 - 2 = b

b = 7

Therefore, our y-intercept is 7! :)

Now that we have both the y-intercept and the slope, we can finally plug this into a new equation, using slope intercept form.

y = mx + b

y = 2x + 7

~Hope I helped!~

A photo that measure 5 inches in length by 7 inches in width is enlarged to 7.5 inches in length. What is the width?
galina1969 [7]

Answer:

10.5

Step-by-step explanation:

You can use ratios to solve this problem.

The original dimensions of the photo is

5 in. by 7 in.

This can be written as:

5:7

And the next is 7.5:?

Then you can use ratios to solve this.

5:7=

7.5:?

5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5

The width is 10.5 inches.
