If y= 2x + 7 were changed to y = 5x+7, how would the graph of the new
function compare with the original?
O
A. It would be less steep.
B. It would change orientation and slant down,
C. It would be steeper.
O
O
D. It would be shifted down.

C is correct

Step-by-step explanation:

Comparing the to equation with slope intercept form:

The second equation has the greatest slope, which is indicating that the line is steeper.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
