What is the answer to questions 4-6?

Step-by-step explanation:

Slope intercept form of a line passing through points is given by where b is the y-intercept i.e, point at which the line intersects the y-axis , m represents the slope given by

4.

b = 1

Equation is  y=2x+1

5.

b = - 5

m = 0 as the line is parallel to x - axis

Equation is y = - 5

6.

b = 4

Equation is

the correct answer is the second option

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
