Question

In this graph, the y-intercept of the line is ? (2,-2,0,-1) . The equation of the line is y= ?(2, -2, 1, -1) x ?(+2, -2, +1, -1)

Answer 1

y - intercept of the line = -2

equation of the line = x - 2

Explanation:

y - intercept of the line is the point in the graph where the line touches the y - axis which in the given case is, -2

equation of the line is,

y = mx + c

where c is the y - intercept = -2

slope, m = y2-y1 / x2 - x1

= -2-2 / -2-2 = -4 / -4 = 1

thus, the equation of the line is, y = x - 2
