Step-by-step explanation:
Given x intercept is 1, So (x,y) is (1,0)
When x intercept is 1 then y value is 0
Another point on the line is (-2,3)
Two points are (1,0) and (-2,3)
Find out slope using the two given points

Use point slope formula
m=-1 and point(1,0)

Point slope equation is

Equation of the line in slope intercept form is

-7 - 3x = 9x(x + 2)
Standard Form:
-9x^2 - 21x - 7 = 0
Answer: For a is 19/15 or 1 4/15
for b I have no clue
Step-by-step explanation: add 3/5 and 2/3
you will get 19/15. In mixed fraction is 1 4/15
The length of a light wave is 3.7 x 10^-6 in scientific notation
Slope is the steepness of a line while the y-intercept is the point where the line crosses the y-axis.
