Find an equation of the line containing the given pair of points (4,1) and (12,7)
1 answer:
Answer:
Y = 3/4 X -2
Step-by-step explanation:
Just apply the equation of a straight line (Y=mX+C), remembering that m represents the gradient of the line. This can be found by dividing the change in the y-axis by the change in the x-axis. Then substitute a set of coordinates with your obtained gradient into Y=mX+C to obtain C, i.e. the y-intercept.

Answer:
Step-by-step explanation:
can be broken down into three fractions, coefficients, powers of p, powers of q.
Simplify the first fraction, then simplify the others by subtracting numerator exponents minus denominator exponents.
The circle is closed and the graph is shaded to the right also there’s a negative on the x, you have to get rid of it first by dividing by -1 and then you switch direction of the less than or equal to greater than or equal because you divided by negative
