The points (3, 10) and (0, 3) fall on a particular line. What is its equation in slope- intercept form? ) Write your answer usin

Mashutka [201]

Answer:

$y = \frac{7}{3}x +3$

Step-by-step explanation:

Slope-intercept formula: $\frac{y_2-y_2}{x_2-x_1}$

$\frac{y_2-y_2}{x_2-x_1}\\\\\frac{3-10}{0-3}\\\\\frac{-7}{-3}\\\\\frac{7}{3}$

$y = mx + b$

$y = \frac{7}{3}x +b$

$3 = \frac{7}{3}(0)+b$

$3 =0+b$

$3 =b$

$y = \frac{7}{3}x +3$

Hope this helps!

Solve for w. <br> 1/7 = -3/2w -4/5 Simplify your answer as much as possible.

Ann [662]

1/7 = -3/2w -4/5
add 4/5 to both sides
1/7 + 4/5= -3/2w
change to common denominator; 5 & 7 go into 35
(1*5)/35 + (4*7)/34= -3/2w
5/35 + 28/35= -3/2w
33/35= -3/2w
divide by -3/2 on both sides; multiply by the reciprocal of -3/2
33/35 * -2/3= w
-66/105= w
simplify by 3
-22/35= w

CHECK:
1/7 = -3/2w - 4/5
1/7= -3/2(-22/35) - 4/5
1/7= 66/70 - 4/5
1/7= 66/70 - 56/70
1/7= 10/70
1/7= 1/7

ANSWER: w= -22/35

Hope this helps! :)
