Expand the following:

3(x + 5)
4 ( x - 4)
2 (5x + 1)

1) 3x+15
2) 4x-16
3) 10x+2

3x+5
4x-4
10x+2

Distribute it by multiplying

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
