Answer:

  • No, there is no proportional relationship

Step-by-step explanation:

<u>The proportional relationship is:</u>

  • y = kx, which is a special form of linear equation, with zero y-intercept

<u>In the given case we have:</u>

  • y = 4.5x + 10

This is a linear function but not proportional relationship because it has y-intercept, different than zero

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).
gavmur [86]

Answer:

y+1=-2(x-5)

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.  

We will substitute m=-2 and x_1=5\\y_1=-1.

y-(-1)=-2 (x-5)

y+1=-2(x-5)

This is the equation of the line with slope -2 that passes through (5,-1).

saul85 [17]

Each can of cat food holds <u>4 ounces</u>

Step-by-step explanation:

We shall assign the ounces of one can as; x

Since the cat is fed  1 can in the morning and 1 and ½ cans in the evening, then the cat eats;

x + ³/2 x ounces per day

This is also equal to 10 ounces

x + ³/2 x = 10

⁵/2 x = 10

x = 10 * ²/5

x = 4

= 4 ounces
