The entire question is: D = 50 - 4m

Slope: -4

Y-intercept: 50

Been a while since I've had to do math like this, cause I don't know how what to do with the last one

Linear function: d = -4m+50 (that's a negative 4 btw)

Slope: -4

y-intercept: 50

I'm truly sorry but I forgot how to do the last one :(

ANSWER

$y = 3x - 3$

EXPLANATION

Let

$y = mx + c$

be the equation.

We can choose any two ordered pairs to determine the equation of the relation.

$(6,15) \: and \: (8,21)$

We find m using the formula;

$m = \frac{y_2-y_1}{x_2-x_1}$

$m = \frac{21 - 15}{8 - 6} = \frac{6}{2} = 3$

The equation becomes

$y = 3x + c$

When x=6, y=15.

This implies that,

$15 = 3(6) + c$

$15= 18 + c$

$15 - 18= c$

$c = -3$

The equation of the relation is therefore,

$y = 3x -3$

Can I have help help on 22,24,26,28,30 please

Dmitriy789 [7]

I'll do 22 for you. 22, 24, 26, 28, and 30, are very similar to each other.

PROPORTIONS:
Draw it out.

5/7 = either c/6, or b/5.
I'll do c/6
5/7 = c/6
solve for c
7c=30
c=30/7
now do the same thing to the remaining side, b.
there!
