Question

What is the equation of the line in slope-intercept form?

Answer 1

Answer:

y = $\frac{5}{2}$ x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 5)

m = $\frac{5-0}{0+2}$ = $\frac{5}{2}$

Note the line crosses the y- axis at (0, 5) ⇒ c = 5

y = $\frac{5}{2}$ x + 5 ← equation of line

Answer 2

Answer:

y  = mx + c

Step-by-step explanation:

m = gradient

c = y-intercept
