if the equation y=-4x+b represents the line that passes throught the point (1,4) determine the value of the y-intercept

y-intercept (0, 8)

Step-by-step explanation:

Plug in (1,4) --> (x,y) and solve for b (y-intercept):

y = -4x + b

4 = -4(1) + b

4 = -4 + b

b = 8

Therefore the y-intercept is (0, 8)

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
