What is the slope of the graph of 3x - 7y = 10 * 3/7 O-37 O 3 O -7
1 answer:
Answer:
Step-by-step explanation:
Solve this for y to determine the slope. Solving for y gets our line into the slope-intercept form, y = mx + b, where the number value of m will be the slope.
-7y = -3x + 10 and
which simplifies down to
The value for m is 3/7 so that is the slope, the first choice given.

Answer:
-4.54 and 1.54
Step-by-step explanation:
This is a quadratic equation
Let Δ be our discriminant :
- a= 1
- b= 3
- c= -7
- Δ = 3²-4*1*(-7)= 37≥0
so we have two solutions : x and y
x =( -3-)/2 = -4.54
y= ( -3+)/2= 1.541
then the solutions are -4.54 and 1.54
