Question

Help 30 points and i will mark brainliest for the best answer which will be more points

Answer 1

Answer:

See below

Step-by-step explanation:

From the table we see there is a relation between x and y values

Every step change of x = 0.5, every step change of y = 2

This relation is linear. The formula for linear function is:

• y = mx + b

Using to pairs of points to get the slope and y-intercept

• (0, 60) and (1, 64)

Calculating the slope:

• m = (64 - 60)/(1 - 0) = 4/1 = 4
• y - intercept is 60 as per point (0, 60)

So the function is

• y = 4x + 60

Part A

• Yes. Described above

Part B

• y = 4x + 60

Part C

• Slope is the steepness of the line.
• y -intercept is the lowest score with no time spent studying
