Question

Help please with question 9

Answer 1

Take 2points

• (0,6)
• (1,7)

Slope:-

`\\ \sf\longmapsto m=(7-6)/(1-0)=(1)/(1)=1`

Equation of line in point slope form

`\\ \sf\longmapsto y-y_1=m(x-x_1)`

`\\ \sf\longmapsto y-6=1(x-0)`

`\\ \sf\longmapsto y-6=x`

`\\ \sf\longmapsto x-y+6=0`

Answer 2

• y = x + 6

Explanation:

According to the graph:

• The line has a y-intercept of 6
• The rate of change is 1 as x and y both increase by 1 unit each.

The slope-intercept form:

• y = mx + b, where m-slope, b- y-intercept

Substitute the values to get:

• y = x + 6
