Question

Help me with question 15 plz?

Answer 1

B

Explanation:

well plug in x and y

so if it says y=2x-3 put it as 7=(2x2)-3 and see if it gives u 7 and if it does di the next set of x and y numbers

Answer 2

B y=2x+3

Explanation:

We need to find the slope of the relationship in the table

m = (y2-y2)/(x2-x1)

= (13-7)/(5-2)

= 6/3

=2

The slope is 2

We can use point slope form to make an equation

y-y1=m(x-x1)

y-7 = 2(x-2)

Distribute the 2

y-7 =2x-4

Add 7 to each side

y-7+7 =2x-4+7

y = 2x+3
