Answer:
m = 3 and c = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 ← is in slope- intercept form
with m = 3
• Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (1, 2) into the partial equation
2 = 3 + c ⇒ c = 2 - 3 = - 1
y = 3x - 1 ← equation of parallel line
with m = 3 and c = - 1
Answer:
x = -1, y = 1
Step-by-step explanation:
2x-y=-3 // y = 2x + 3 (eqn 1)
3x+y=-2 (eqn 2)
sub 1 into 2
3x + 2x + 3 = -2
5x = -5
x = -1
sub x = -1 into eqn 1
y = -2+3
y = 1
Answer:
f + 3
Step-by-step explanation:
Combine like-terms
4f - 2f - f +3
f + 3
Answer:
None of the above
Step-by-step explanation:
A proportional relationship is where one ratio is the same as another ratio. For example, the ratio 1:2 is the same as 2:4. If you go ahead and divide both of these ratios, you'll get the same relationship 1:2.
