Question

The equation of the line is ___

Answer 1

y = -2x + 3

Explanation:

→ We know the slope so we can automatically plug that into the y = mx + c formula so,

y = -2x + c

→ Now we substitute in the coordinates (0,3) to find the c value and therefore complete the equation

y = -2x + c

3 = ( -2 × 0 ) + c ⇔ 3 = 0 + c ⇔ c = 3

y = -2x + 3

Answer 2

Since the slope is -2 and y-int. is 3 the slope-intercept form is y = -2x + 3 which in standard form is 2x + y = 3.
