Answer: y = 4x + 11
Explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis represent
The given line passes through
(- 3, - 1) and the slope is 4
To determine the intercept, we would substitute x = - 3, y = - 1 and m= 4 into y = mx + c. It becomes
- 1 = - 3 × 4 + c
- 1 = - 12 + c
c = - 1 + 12
c = 11
The equation becomes
y = 4x + 11
