Question

What is the equation of this graphed line?

Answer 1

Answer:

• y = -9/8x + 7

Step-by-step explanation:

Slope-intercept form is:

• y = mx + b

Points given:

• (0, 7) and (8, -2)

y-intercept is

• b = 7 as per the first point

And the slope is:

• m = (-2 - 7)/(8 - 0) = -9/8

So the line is:

• y = -9/8x + 7

Answer 2

Answer:

Required Answer:-

points are

• (0,7)
• (8,-2)

slope =m

${:}\longrightarrow$$\sf m={\dfrac {y_2-y_1}{x_2-x_1}}$

${:}\longrightarrow$$\sf {\dfrax {-2-7}{8-0}}$

${:}\longrightarrow$$\sf {\dfrac {-9}{8}}$

y intercept:-

7

Hence the equation is

${:}\longrightarrow$$\sf y={\dfrac {-9}{8}}+7$
