What is the y-intercept of the line shown? (4 points) A coordinate plane is shown. A line passes through the y-axis at -1 and through the point 1 comma 2.

-1

Step-by-step explanation:

the equation that presents this sentence is. y=1/3x-1. -1 is the y intercept which passes at the y axis line.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

b. x- 48 =120
