topjm [15]

Answer:

<h2>y = 2x+4</h2>

Step-by-step explanation:

$A(-3,-2) and B(1,6).\\\\x_1 = -3\\y_1 = -2\\x_2 = 1\\y_2 =6\\\frac{y-y_1}{x-x_1} =\frac{y_2-y_1}{x_2-x_1} \\\frac{y -(-2)}{x -(-3)} =\frac{6-(-2)}{1-(-3)}\\\frac{y+2}{x+3} = \frac{6+2}{1+3} \\\frac{y+2}{x+3} = \frac{8}{4} \\Cross-multiply\\4(y+2) =8(x+3)\\4y +8 =8x+24\\4y = 8x +24-8\\4y = 8x+16 \\OR\\ y = 2x+4$

here we have 1 in 4 parts

if we consider 1 as 16/16 and 1/2 as 8/16

and also the 3rd unit i mean 3/4 is 12/16

so it would be approximately right to say the point is showing somewhere about 9/16

ALGEBRA by bundling cellular land line high speed internet connection and cable service Joyce abbot was able to save 48.50 per m

andreyandreev [35.5K]

Answer: She should budget $672.89 monthly next year for this service.

Step-by-step explanation:

Since we have given that

Amount he was able to save per month = $48.50

Total amount he spent for the year = $1254.89

Amount he saved for the year would be

$48.50\times 12\\\\=\$582$

Amount left from total would be

$1254.89-582\\\\=\$672.89$

Hence, She should budget $672.89 monthly next year for this service.
