3(5b-1)=5<br> solve for b<br><br> 4(3y-1)=20<br> solve for y

Gnom [1K]

3(5b-1)=5
Get rid of the brackets
15b-3=5
add 3 to both sides of the equation
15b=8
divide both sides of the equation by 15
b=0.53

4(3y-1)=20
12y-4=20
12y=24
y=0.5

For the straight line defined by the points (2,55) and (4, 87), determine the slope (m) and y-intercept?

mamaluj [8]

Answer:

Slope(m) = 16

Y intercept (c) = 23

Step-by-step explanation:

Given:

Points : (x1, y1) = (2, 55)

(x2, y2) = (4, 87)

Using two point form to calculate slope:

$m = \frac{y2-y1}{x2-x1}$

$m = \frac{87-55}{4-2}$

m = 16

To find y intercept:

Take any one point ans slope :

Using slope point formula:

y = mx + c

87 = 16(4) + c

Solving for c:

c = 23
