Find the equation of the line with x-intercept 4 and y-intercept -1 in slope-intercept<br> form.
Nastasia [14]

Answer:

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-coordinate of the y-intercept, so we can already conclude that b=-1.

This results in y = mx - 1

We also have the x-intercept, and we know that the y-coordinate of an x-intercept is always 0. This means that we have the point (4,0). Substitute this into the formula to generate m:

0 = 4m - 1

4m = 1

m = 1/4

thus y = \frac{1}{4}x - 1

Please help!! Write the sum using summation notation, assuming the suggested pattern continues. -9 - 4 + 1 + 6 + ... + 66
fiasKO [112]
r=-4-(-9)=-4+9=5 \\  \\ a_{1}=-9 \\  \\ a_{n}=66 \\  \\ a_{n}=a_{1}+(n-1)r \\  \\ -9+5(n-1)=66 \\  \\ -9+5n-5=66 \\  \\ 5n-14=66 \\  \\ 5n=80 \\  \\ n=16 \\  \\ S_{n}= \frac{a_{1}+a_{n}}{2} *n \\  \\ S_{n}= \frac{-9+66}{2}*16=57*8=456
