Answer: Yes, the answers in the blanks are correct.
Step-by-step explanation: The easiest way to answer this question is to plot the points onto a graph. The point (0,10) is right on the y-axis, so that would be the y-intercept. The best way to find the slope is the rise over run method. The slope 2/5 is correct because it "rises" by 2 units and "runs" by 5 units.
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
