Question

Please help me with this problem! :)

Answer 1

y = 2x + 7

Explanation:

Given the equation is in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

We can see from the point (0, 7) that c = 7

Calculate the multiplier using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 7) and (x₂, y₂ ) = (1, 9) ← 2 ordered pairs from the table

m =
`(9-7)/(1-0)` = 2, hence

y = 2x + 7 ← equation relating x and y

Answer 2

2

Explanation:

y = 2x +7

so,

if x=0 then y =2 x 0 +7 =7

if x=1 then y =(2 x1) +7 =2+7=9

if x=2 then y =(2 x2)+7 = 4+7 =11

if x=3then y =(2 x3) +7 = 6+7 =13

if x=4 then y =(2 x4) +7 =8+7 =15

if x=5 then y =(2 x5) +7 = 10+7 =17
