Aline has a slope of –3 and a y-intercept of 3. what is the x-intercept of the line? a: –9 b: –1 c: 1 d: 9

A line has a slope of -3 and a y int of 3

In y = mx + b form, the slope will be in the m position and the y int will be in the b position. So ur equation for this line is y = -3x + 3.

To find the x int, u sub in 0 for y and solve for x
y = -3x + 3
0 = -3x + 3
3x = 3
x = 3/3
x = 1 <=== ur x intercept
