Question

What’s the slope m and y-intercept b of both these images?

Answer 1

Slope = 1

y-intercept = 3

Explanation:

Since, slope of a line passing through two points
`(x_1,y_1)` and
`(x_2,y_2)` is given by,

Slope =
`(y_2-y_1)/(x_2-x_1)`

Therefore, slope of the line passing through two points (0, 3) and (-3, 0) will be,

Slope =
`(3-0)/(0-(-3))`

Slope = 1

y-intercept of the line = distance between the origin and point of intersection of the line with y-axis

y-intercept = 3
