Please answer these questions. It is only two questions and they are super small. I have put the picture of the question down below.

9. y= ¼x -5

10. y= 2x +18

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope (also known as gradient) and c is the y-intercept.

9. The given equation is already written in the slope-intercept form. The coefficient of x is ¼, thus the gradient of the given line is ¼.

Parallel lines have the same gradient and hence, gradient of line is also ¼.

Substitute m= ¼ into the equation:

y= ¼x +c

To find the value of c, substitute a pair of coordinates.

When x= 8, y= -3,

-3= ¼(8) +c

-3= 2 +c

c= -3 -2

c= -5

Thus, the equation of the line is y= ¼x -5.

10. Gradient of given line= 2

Parallel lines have the same gradient.

Thus, gradient of line= 2

Substitute m=2 into the equation:

y= 2x +c

When x= -4, y= 10,

10= 2(-4) +c

10= -8 +c

c= 10 +8 (+8 on both sides)

c= 18

Therefore, the equation of the line is y= 2x +18.
